Ask many a wizened old motorcycle guru what their favourite motorcycle ever is, and they would say… the Triumph Street Triple.

… well, the truth is they may say any old thing. Man, the number of people who’ve told me any random bike is the “best bike of all time” for whatever reason! So many bikes — it’s a wonderful time to be alive.

But the Triumph Street Triple, or “Striple” as it’s affectionately called, really is a bike for many people. It just ticks so many boxes:

  • Comfort: It’s upright (ish), so you don’t have to lose all feeling in your hands just to ride for an hour
  • Power: It makes a lot of power (over 75 kW or 100 hp) in stock trim. It’s the “right amount” for a lot of situations
  • Character: It has a blaring triple, for that bellow at high revs
  • Torque: It’s more tuned for a broad spread of mid-range torque than 600cc sport bikes, not outright power above 14,000 rpm, so you can actually ride it down to the shops to get a coffee where you can sit and admire what you rode there
  • Lightness (or a “lack of weight”): in stock trim these are light bikes for their class (or any class)

What’s the downside? There isn’t one! The only downside to the Street Triple, I suppose, is that it’s not another (different) kind of bike, like the much more powerful Speed Triple or the much more adventurous Tiger 800 / 900.

See here for all the other middleweight naked sport bikes available.

But wow, the Street Triple is a perfect bike if you (like me) like the screaming midrange of a 600 cc bike but don’t want to wait until 6000 rpm to start enjoying life.

Right from 2-3K, a Street Triple never feels slow. People like to throw truisms about triples around, but with this bike they’re true: Street Triples are tuned for the low-end torque of a twin, but the top-end of a four-cylinder sport bike (at least before rpms get into the silly range).

OK, so now you want a Street Triple too. Welcome to the club!

But sadly, Triumph has gone and made it very confusing in recent years, constantly rearranging their model codes, changing what it means to have a Street Triple R or S, and making it different by where you live — what you get is slightly different if you’re in Europe, the US, or Australia/New Zealand.

This all started for me when I visited a dealer years ago and the guy tried to explain to me that both models I was looking at had Brembo brakes, but one was better. (Which resulted in me putting together a definitive braking systems FAQ, by the way.)

I’ve been looking at Street Triples of all generations, looking for an older one (found one but it got away before I pulled the trigger… story of my life / this website), and thought I’d share everything I’ve learned from test rides, research, speaking to people, and bothering netizens on forums about what their favourite tyre is (kidding. Also, don’t tell me. Obviously, it’s the Pirelli Ultra Doppio Macchiato Diablo Rosso Oscuro VII.)

Updated for the 2023 models, the 5th generation of the Triumph Street Triple, with an IMU and even optional cruise control.

I’ve done my best to present this buyers’ guide correctly, but I keep discovering new bits of information around the Internet. If you find any egregious omissions, please let me know!

Triumph Street Triple — A Brief History

The Street Triple is part of the new generation of Triumph motorcycles since John Bloor took over the defunct brand in the 1980s.

The more experienced riders among us remember the “old” Triumph brand, a company founded a century ago that made cars and then motorcycles.

That was a different Triumph. I know because one of our family’s early cars was a Triumph, and it was quite different to anything else from Triumph I’ve seen before. In fact, a neighbour gave it to my father for free (because, it turned out, it was cursed), and my dad later sold it for $150 and was surprised anyone paid anything for it. (The new owners were pretty drunk and crashed it a couple of blocks away and left it there.)

Anyway, some quick googling shows that the Triumph Cycle Company was actually a separate legal entity that produced motorcycles since 1902.

The original Triumph made a bunch of iconic bikes but eventually went bankrupt. Not because the bikes were bad, but just that the changing global economy made them uncompetitive. They went bankrupt in 1983.

John Bloor, a now-famous British billionaire businessman, was shopping for factory property, and along with the property bought the rights to the brand that same year, in 1983. For a while, he let others build motorcycles under the Triumph brand, but eventually made the now historically smart move to rebuild the Triumph motorcycles brand up from scratch. This generation is also known as the “Hinckley” generation.

The original Triumph brand coined a lot of model names that the new Triumph has reproduced in later days: the Daytona, the Speed Twin, the Trident, the Bonneville of course, and others.

But even though the original Triumph did make three-cylinder engines (like the Trident), they never had any bike called the “Street Triple” (nor “Speed Triple”).

Triumph announced the first Triumph Street Triple in 2007 for the 2008 model year. They conceived it as a smaller sibling to the Speed Triple (then with a 1050 engine), and heavily borrowed from the Triumph Daytona 675 of the time, taking its engine, and much of its frame.

But the original Street Triple, a bug-eyed naked, looks very different from the Daytona, a racy sportbike.

Those dual round headlights really caught people’s eyes. What a look!

Sadly, Triumph decided to abort the dual round headlights by the 2012 model year and never really brought them back. The latest Triumph Street Triple RS looks fantastic by other measures, but it lost that original look. In the early 2010s there were many threads on forums about how to convert back to the original round headlight look.

I’ve gotten used to and actually appreciate the new look. It looks lean and fast. But it’s all a matter of personal taste.

That original Street Triple, which you can still find for sale, manages to squeeze out 78 kW (105 hp) from its 675cc three-cylinder engine. Peak power comes on at 11850 rpm, and peak torque is at 9750 rpm.

The original Street Triple 675’s power is down on the Daytona 675’s 91 kW (125 hp) peak power, of course.

But what is more amazing was how that torque is delivered in the Street Triple — including any later generation.

The engine of any Street Triple is a lot more torque-forward than its stablemate the Daytona and other ~600-class street bikes. (I say ~600 class because this is 675cc, and anyway, the Kawasaki ZX-6R has been 636 cc for most of its life.)

Down low from 2500-3000 rpm, the 675cc motor makes 75% of its peak torque. This is quite different to other 600cc-class bikes, which make maybe half their peak torque at lower revs.

At the 7000 rpm range there’s still a jump in torque, but it’s not like the turbocharger feeling you get with a 600cc sportbike.

In sportbike terms, this torque curve is relatively “flat”.

Here’s an annotated dyno chart (based on data from an old Cycle World dyno run) to explain visually:

Triumph Street Triple 675 dyno chart torque curve (annotated)
2008 Street Triple 675 torque curve from dyno runs

What is less often emphasised about the original Street Triple is how light it is.

The first Triumph Street Triple weighs only 182 kg / 401 lb wet (fully fuelled). Later generations keep this spirit — the mid-spec 2017 Triumph Street Triple R weighs under 180 kg / 397 lb, even though it has a lot more rider aids and a bigger engine!

In fact, the claimed weight for a fully-laden Street Triple of whatever incarnation has always been between 175 and 182 kg (386 – 401 lb) — and since that’s a small difference, and things like the weight of the rider plus gear, accessories/weight reducing add-ons, and fuel in the tank would make a bigger difference — I’m not going to report individual differences in the model history. It’s just worth noting that the weight never ballooned out.

For comparison’s sake, here are a few other somewhat comparable bikes, power, and weight, all 2021 model year:

Motorcycle year/make/modelPeak Power Wet WeightPower/Weight (kW/kg)
2021 Triumph Street Triple RS (765cc)85 kW175 kg0.49
2021 Kawasaki Ninja ZX-6R 636 (636cc)95 kW196 kg0.48
2021 Yamaha MT-09 SP (890cc) 87.5 kW189 kg0.46
2021 Ducati Monster (937cc)82 kW188 kg0.44
2021 KTM 890 Duke (890cc)79 kW184 kg0.43
Power/weight ratios of some common middleweight sport bikes

See here for a buyer’s guide to the Yamaha MT-09.

So the modern Street Triple R does very well. Yes, that’s in metric units and not “freedom units”, but believe me, the order of the ratios is the same if you do it in brake horsepower over pounds. (Or Pferdestärke / kg, or whatever.)

And just for fun… the little Kawasaki Ninja 400, itself a very lightweight bike, weighs 168 kg — barely lighter than the Street Triple RS, which has around three times the peak power, and much higher spec everything.

There are lighter naked bikes, like the Aprilia Tuono 660, but they’re not as powerful. And there are more powerful naked bikes, like the Ducati Streetfighter V4S, which have higher power to weight ratios too, but they’re heavier and in a different class of bike and budget.

Over the years the Street Triple has had some significant changes. I’ll go over these in more detail in the next sections:

  • 2007-2011: “Original spec” — round headlights, upswept exhaust, and the 675cc engine.
  • 2009-2011: First Street Triple R, with better suspension and brakes
  • 2012: Strange unicorn year for both the original and the R with the new headlights, no ABS yet, but still an upswept exhaust.
  • 2013-2016: Cosmetic redesign for both base spec and R, with different front lights and an underbody exhaust (for emissions as well as mass centralisation, and optional (sometimes standard) ABS.
  • 2014-2018: Original Triumph Street Triple 660, the low-power LAMS class (Aust/NZ)
  • 2014-2016: Higher-spec Rx (like an R but with a bunch of add-ons standard)
  • 2017-2019: New redesign with a 765cc engine. Three different states of engine tune in the Street Triple S, Street Triple R, and Street Triple RS.
  • 2020+: Street Triple R and Street Triple S repositioned slightly. In the UK, the S became the 660 cc low-power A2 / LAMS bike. The R lost the TFT display and some dollars.

More detail on all these generations below.

Street Triple Generations and Models Summary

It drives me slightly crazy when motorcycle manufacturers barely change (or don’t change) the name of a model but make massive changes inside it, either for a different time period or different market.

But it also gives me a job to do — do the research and explain it all for you, the eager buyer!

Over the years and in different regions, the Street Triple R and S in particular can mean different things. For example, regarding the Street Triple S:

  • In the UK, this is 660cc and can be bought in restricted and unrestricted form.
  • In Australia, it’s 660cc and is always restricted. (Unless you derestrict it)
  • In the US, it’s 765cc and never restricted, though it’s lower spec than the R and RS.

It makes sense if you stick to one market — but when we start googling things about a model, and we find figures from the UK/Europe, the US and Australia, it becomes bamboozling.

At least early models are the same everywhere. More reason to buy used!

Generations of Triumph Street Triple

More details on all these model variants below.

1st Gen Triumph Street Triple – 2007-2012

This is the Street Triple that started it all. It was just called the “Street Triple”, not the “Street Triple 675” or whatever we use to distinguish it from later generations.

At its core, the first Triumph Street Triple is a pared-down Daytona 675 with a street tune and different road-going equipment — different lights, handlebars, and exhaust.

Key characteristics of the first-gen Street Triple (2007-2011) are:

  • Round headlights
  • 675cc engine from the Daytona — fuel injected inline three-cylinder engine
  • 79 kW (106 bhp) @ 11,750 rpm
  • 68 Nm (50 ft-lb) @ 9,100 rpm

The base model first-gen Striple has no adjustability in suspension, but has a preload-adjustable rear shock (though they don’t supply you with the spanner to do it).

Unless you find an absolute bargain, or one on which someone has replaced the suspension, it’s nearly always a better idea to get an early Street Triple R with adjustable suspension.

On the other hand… this is the original Street Triple. They’re not very expensive, they look cool, and they’re classics. You could also rebuild the suspension for exactly your ride style and weight, and you might have a bargain.

1st Gen Triumph Street Triple R 2009-2011

The 2009 Triumph Street Triple R is the first “R” in the series.

Triumph took the base model Street Triple and added:

  • Fully adjustable front suspension (a KYB 41mm fork) borrowed from the Daytona
  • 4-piston calipers, still Nissin and on the same 308mm disc
  • Fully adjustable rear shock

Basically Triumph took more premium parts from the Daytona 675 of the time and plonked them on the Street Triple R. And a track legend was born!

The 2009-2012 Triumph Street Triple R still has short gearing, round headlights, and exhaust pipes under the seat. This combination makes the original 2009-2012 Triumph Street Triple R an iconic hooligan machine.

If you’re after an original round-eyes Street Triple, I’d pick the Street Triple R over the base model (all other things equal). You’ll save money when it becomes time to upgrade the suspension of the original.

Of course, if you find an original Striple in great condition for a good price, do what’s right for you!

2012 Triumph Street Triple and Street Triple R — the “Last Hurrah”

The 2012 Triumph Street Triple and Street Triple R is a peculiar unicorn year in the Triumph Street Triple’s history.

Triumph just replaced the headlights, but kept everything else in the motorcycle the same. Same exhaust, no ABS, etc. In the R version they also kept everything else the same (better brakes, suspension).

AMCN called it replacing the “Marty Feldman” eyes with “Dame Edna’s Glasses” headlights, a reference which requires you to be Australian to understand.

Marty Feldman –> Dame Edna

Great, now I can’t un-see it…

2nd Gen Street Triple – 2013-2016

In 2013, Triumph did the unthinkable and permanently ditched the round eyes and the under-seat exhaust.

But they managed to reduce the weight, so not many complained.

Key changes for the 2nd gen Triumph Street Triple include:

  • Major aesthetic change to the headlights — same as the 2012
  • Side-slung exhaust, rather than under the seat
  • Lighter frame, exhaust, wheels, and rear caliper, leading to 6 kg (13 lb) less weight (non-ABS model)
  • More forward weight bias — 52% front, up from 49% front, for more precise handling
  • Taller first gear
  • 310mm front rotors (up from 308)
  • Optional TPMS

2nd gen Street Triple Base model (2013-2016)

The base model of the 2nd gen Street Triple has the same engine (with the same specs) as the Street Triple R.

You can recognise the Street Triple base model by the gold fork tubes. Despite the bit of bling, the forks are non adjustable on the base 2013-2016 street triple. And the monoshock is adjustable only for preload.

2nd gen Street Triple R (2013-2016)

This is my pick of the bunch to buy used.

If you find a 2013-2016 Triumph Street Triple R with ABS for a decent price and low miles — particularly if it was fixed with the ex-works Arrow exhaust — pick it up.

The 2nd gen Triumph Street Triple R took the base model and added:

  • Fully adjustable front and rear suspension (only a preload adjustable shock on the non-R)
  • 4-piston radial-mounted calipers with optional ABS (2-piston on the non-R)
  • Adjustable swingarm pivot (not available on the non-R)
  • Slightly steeper rake and slightly shorter trail, and also slightly higher seat height (from the suspension differences)

You can spot a Street Triple R easily from the red subframe, black fork tubes, matching radiator cowls, and red pinstripe wheels.

Triumph Street Triple 660 (First gen LAMS bike, 2014-2019)

Red 2014 Triumph Street Triple 660 RHS studio

In Australia and New Zealand — maybe elsewhere, not sure — Triumph released a first generation of the Street Triple 660, based on the 2013-2016 Street Triple. It’s carefully designed to meet the Australia/New Zealand LAMS requirements of making a maximum of 150 kW per (metric) tonne and being under 660 cc in capacity.

This version is different from the 2020+ Street Triple S in at least the name (but they also ride differently, too).

The 2014-2019 version of the Street Triple 660 is based on the 675 motor with a slightly shorter stroke, trimmed from 52.3mm to 51.1mm. Triumph also altered the cam timing and of course re-programmed the fuel injection to dramatically reduce the peak power by around 50% to the legal maximum in Australia and New Zealand, but also to maximise torque. You can spin the wheel up pretty easily on the 660.

The bike is otherwise the same as the base model Street Triple — non-adjustable front suspension and a Nissin two-piston caliper. It looks the same other than a decal that says “660” on the back rather than “675”. A lot of people remove this decal on the used market.

The learner market is pretty fierce in the Antipodes. Since a number of years ago, people have had to ride learner bikes for 2 years (roughly) before they can move to an unrestricted “full power” license. In this time, many people move on from the bike hobby altogether, meaning the market is saturated with learner-legal small capacity bikes.

In this field, the Street Triple 660 is very popular. It’s a Triumph, and it looks and sounds cool. It has a lot of torque from down low and really doesn’t feel like a learner bike, just a learner-legal bike. It’s more expensive than the usual competitors, too.

In 2017, the Triumph Street Triple 660 got a visual makeover in line with the other 2017 bikes. I’m not sure if the engine was changed. The 2017-2019 Street Triple lost the 660 decal and otherwise looks like the 2017 base model.

I haven’t found official Triumph photos for this era (I did, but they’re the wrong photos on the Triumph website… SMH), but know that in 2017-2019 they’re different from scouring for sale ads!

Triumph Street Triple Rx (2015)

In 2015 Dr. Triumph prescribed the Rx model of the Triumph Street Triple.

As you might be able to guess, the Rx is a special version of the R. More R!

The Triumph Street Triple Rx has much the same specs — same engine, brakes, and suspension.

But Street Triple Rx gets the following as standard:

  • Quickshifter (a frequently chosen option)
  • A standard fly screen, seat cowl, and belly pan (fairly commonly added)
  • Diablo red wheels and special decals

The rest is basic Street Triple R. If you get a Striple R and add on a quickshifter and some plastic bits, you’ll basically have the Rx.

3rd gen Street Triple (2017-2019): The 765 cc engine

2017-2019 Triumph Street Triple Family 1 Web
2017-2019 Triumph Street Triple Family All models

Triumph in 2017 updated the Street Triple to 765 cc. This really surprised me when they did this! I actually thought it was a typo (675 / 765). Five years later, I’ve mostly gotten used to it.

The banner update is that Triumph increased engine capacity to 765cc. That much is obvious. The engine is still a three-cylinder 12-valve liquid-cooled motor with the same personality — a lot of torque across the whole midrange.

Here’s a composite dyno run from Cycle World dyno runs showing the difference.

Street Triple 765 vs 675 Engine Speed Torque
Rear Wheel Torque — 675 vs 765 RS

Since the data is from different runs, don’t focus on the exact numbers; rather, just acknowledge two things:

  1. Like before, the torque curve of the Street Triple is incredibly flat.
  2. The 765 makes ~10% more torque than the 675 across the whole rev range.

Yes, the above data is from the RS, which is tuned for more power.

Oh yeah, Triumph took the unusual step of tuning the different spec Street Triple engines with the 765 engine for different power levels. There’s a difference of roughly 5% power between the Triumph Street Triple S and R, and the same between the R and RS.

I only rarely see other brands have different power specs within one model line. Triumph, for example, has various spec levels of the 1200 motor between motorcycles of the 1200-class Modern Classics line (the T120, Scrambler, Speed Twin and so on), but the specific types of Triumph Scrambler have the same spec motor.

But anyway, there’s a different peak power and torque spec for each of the 2017 Triumph Street Triple S, R, and RS models.

Other than changing the engine, the bikes look and function pretty much the same. But Triumph did go and change the model line-up slightly with some different letters.

2017-2019 Triumph Street Triple S — the 660cc A2 / LAMS-compliant version

2017-2019 Triumph Street Triple 660 A2 LAMS
2017-2019 Triumph Street Triple 660 A2 LAMS. Looks the same as the 765.

From 2014-2016 there was the Street Triple 660 released in Australia and New Zealand. From 2017 onward this was also available in the UK and Europe for A2 licensing laws.

Let’s start with the base spec, which has been a very popular learner bike for Europe, Australia, and New Zealand. (Skip over this if you’re from the States, unless you’re curious about this weird 660 cc version.)

Europe’s learner licensing laws are different from those in most states of Australia and NZ. But this model satisfies them all.

At its base, the 2020 Triumph Street Triple S has a 660 cc (actually 660, not 659 like the previous) engine with a reduced bore AND stroke vis-a-vis the 765 motor.

In the UK it makes peak power of 35 kW / 47.6 PS and 60 Nm peak torque (at 5250 rpm) for A2 license compliance, but here’s some magic: a dealer can de-restrict it to 70 kW / 95.2 PS and 66 Nm peak torque.

In Australia there’s no mention that a dealer can “de-restrict” your bike. This is probably because it involves a more complex process to re-register your Street Triple S as a full-power bike, which is just as complex if you ever decide to go the other way. For this reason, I would not recommend it, as it’d be much easier to sell your bike (LAMS-class bikes make up a huge portion of the market) and move on than to sell a de-restricted but still lower-power and lower-spec 660cc Street Triple.

I’ve seen some reports that the 2017+ Street Triple 660 continues to make 40 kW / 54 bhp (55 PS) in Australia/NZ, but I’m not sure. They just might be incorrect carry-overs from the previous generation. It doesn’t matter too much. It behaves like the former bike — fast at normal speeds, but if you wind it out past 10000 rpm you might be disappointed.

You can pick a new gen Street Triple 660 by the calipers — they look a bit different to the original Street Triple 660 (black, vs the original gold ones on the S).

2017 Triumph Street Triple S 765 cc (2017-2019)

2017 2018 2019 Triumph Street Triple S 765 Black RHS diagonal
2017-2019 Street Triple S 765

Triumph’s 2017-2019 Street Triple S is the entry-level 765 cc “full-power” motorcycle. It’s conceptually the same as the earlier base model Street Triple (non-R) — it has street-level lower-spec brakes and suspension.

The 2017-2019 Street Triple S is a bike that is totally fine and still a blast to ride. For the everyday rider who doesn’t intend to get hard on the brakes around corners — i.e. people who just want to commute on a cool bike — the Street Triple S is a great option.

Not great enough it seems, though, as Triumph discontinued this concept of bike from 2020. They actually kept making a bike called the Street Triple S, but changed the engine. (*Shakes fist at sky*)

The 2017-2019 Street Triple S 765 makes peak power of 83.1 kW (113 PS / 111.4 bhp) at 11250 rpm, and peak torque of 73 Nm (54 lb-ft) @ 9100 rpm. Healthy.

There’s a non-adjustable KYB fork, a preload adjustable KYB shock, twin 310mm discs, and 2-piston Nissin calipers.

It comes with analogue instruments and two ride modes.

If you’re unsure which one you’re looking at… the decal just says “Street Triple”. But the brake caliper and the instruments will confirm what you’re thinking.

The Triumph Street Triple S is gradually disappearing from most catalogues. Predictably, it’s just less attractive than the 2021 Triumph Trident.

Even though it’s on some websites (e.g. France), if you go to a showroom, you’ll see a bunch of Tridents there. If I were on a restricted license, I’d pick the Trident, too.

2017-2019 Street Triple R

The “mid-spec” Triumph Street Triple R (2017-2019) is actually quite high-spec! It’s a bit higher spec than the R that came from 2020 onward.

Like the S, it gets a 765cc triple, but the engine makes slightly more power — peaking at 86 kW (118 PS / 116 bhp) at 12000 rpm.

The Street Triple R comes with an adjustable KYB Separate Function-Big Piston fork (SF-BPF), with preload adjustable on the left fork leg, and rebound and compression damping adjustable on the right. The R has Brembo M4.32 calipers. And the 2017-2019 version of the Street Triple R comes with a TFT display, the same as on the RS.

The Street Triple R 2017-2019 comes with four ride modes — Road, Rain, Sport, and Rider (programmable).

This bike is really the bike for most people. It’s a sport bike with enough spec to satisfy nearly anyone. If you are a track pro then you might want the Öhlins shock and Brembo M50s of the RS, but then again, you can just get the R and swap in whatever suspension and brakes you like.

Triumph kept the same engine spec in the 2020+ Street Triple R, but took away the TFT display, and also shaved some money off the sticker price.

Triumph Street Triple RS (2017-2019)

Here we go. The original Street Triple RS.

Again, it has a 765 cc engine, but tuned slightly higher than the R, making 90.4 kW (123 PS / 121.2 bhp) @ 11700 rpm.

Front suspension seems to be the same 41mm fork, but it’s actually a BPF, rather than SF-BPF. This means that the fork legs are the same — you adjust preload, rebound damping, and compression damping on both. This gives experienced riders more ability to fine-tune settings.

The rear shock is an Öhlins STX40 piggyback reservoir monoshock, a big upgrade from the Showa shock on the base model.

Brake discs are the same 310mm floating ones, but the caliper is a Brembo M50 unit, which we first saw on the Ducati 1199 Panigale. That’s a fast bike. The M50s should be good enough for any mortal on the RS.

Finally, you get another ride mode — a customisable Track mode — on the RS, for a total of five ride modes (up from four on the R).

From 2020 Triumph only slightly improved the RS. It was already a winning formula.

4th Gen Street Triple (2020-2022): Simpler line-up

In 2020, Triumph re-positioned its models into

  • Street Triple S, a 660cc model not available everywhere — this is essentially the same as the 2017-2019 Street Triple 660 but visually a little different (e.g. no more decal)
  • Street Triple R, slightly lower spec but also cheaper, and including a low ride height variant
  • Street Triple RS — Pretty much like the 2017, but more mid-range torque

2020+ Triumph Street Triple S

This is basically the same bike as the 2017-2019 Street Triple 660 A2 / LAMS-compliant bike, so I won’t dwell on it for long. But it looks newer — see the updated graphics and lights.

2020 Triumph Street Triple S

From 2020, Triumph decided to rename the artist formerly known as the Triumph Street Triple 660 or Triumph Street Triple A2 as the Triumph Street Triple S.

It’s the same fundamental bike, with a 660 cc lower-power motor that meets either A2 or LAMS spec.

To avoid too much confusion, Triumph stopped selling any S variant in the States (it was previously a 765 cc, slightly lower-power and lower-spec version than the R and RS, but higher-power than a de-restricted 660… are you still with me?). The S worldwide is now the 660 (well, 659) cc Street Triple.

You can pick the Street Triple S by the decal and generally different look. Hopefully owners will leave that decal on!

2020-2022 Triumph Street Triple R — The New Mid-Spec

I like what Triumph has done — made a “mid-spec” Triumph Street Triple R. I like it because I happen to like analogue tachometers.

2020 Triumph Street Triple R — Matt Silver Ice

The modern Street Triple R has the same basic engine as the Street Triple RS, but it’s tuned ever so slightly lower, for a peak of 116 hp at 12000 rpm, and peak torque of 57 ft-lb at 9400 rpm. I challenge you to tell the difference!

The lower power comes from a range of internal changes, but it does result in a slightly lower (but still high) 12.50:1 compression ratio.

The R still comes with many of the nice bits as the Street Triple RS, including fully adjustable front Showa suspension. Just bear in mind that like the previous version R, the fork on the front is a Showa “Separate Function — Big Piston Fork” (SF-BPF).

The difference is that the RS has a straight “Big Piston Fork” (BPF).

On an SF-BPF, you modify preload on one side, and rebound/compression damping on the other. On BPF, you modify all three things on both fork tubes.

The difference… well, anecdotally, the SF-BPF is fine for most people, even people who enjoy track days, but the BPF is what you’d get if you’re a serious top-group racer. Or get BPF if you just want the best.

The 2020 model even comes with a quick shifter standard. It was previously an option (that many went for).

But the Street Triple R makes some small sacrifices in that it forgoes the Öhlins rear shock for a Showa unit — that’s still fully adjustable, mind you.

Brakes on the R are on the same 310mm floating discs, but the calipers are “merely” Brembo M4.32 units — still radial monoblock calipers, and the same spec as those found on many high-end sport bikes, like the Suzuki GSX-R1000.

Finally, the 2020-2022 Street Triple R comes with an analogue / digital instrument cluster, just like on your favourite retro Casio watch. This is a cost-cutting and price-saving step back from the 2017-2019 TFT.

I’ve read some potential owners are really turned off by the 2020-2022 R lacking a TFT, considering some direct competitors have it (e.g. the BMW F 900 R, Kawasaki Z900, and later the 2021 Yamaha MT-07). I do think it’s weird to take a feature off an existing model. It makes the 2017-2019 Street Triple R look like a good used buy.

That’s the best bit — the 2020-2022 Street Triple R is cheaper than the old one.

2020-2022 Triumph Street Triple RS — The Ultimate

Triumph Street Triple RS 2020 Silver Front Right 3-4
2020 Street Triple RS

The 2020 Street Triple RS is much like before, based on a high-power engine that makes 121 bhp @ 11750 rpm, or 58 lb-ft at 9350 rpm, with a high 12.54:1 compression ratio.

As before, this is slightly more peak power than the Street Triple R, thanks to its slightly higher compression ratio. But the 2020 Street Triple RS, which is Euro 5 compliant, makes more peak torque (79 Nm vs 77 Nm at 9350 and 9400 rpm respectively), meaning more mid-range power.

Triumph continues to distinguish the modern RS with its higher-spec suspension and brakes. It has the same front suspension as the R, though at the bottom of the forks you’ll find Brembo M50 calipers, the same that you find on superbikes of a few years ago.

And at the rear there’s an Öhlins STX40 shock, the same as on the previous gen.

The 2020 version of the Street Triple RS gets a few other niceties:

  • Daytime Riding Lights (DRLs) — exclusive to the 2020-2022 RS (neither the contemporaneous R nor the previous R or RS got it)
  • Five riding modes (same as the previous R, but the same gen R just has 3)

Other than that, one interesting thing is that the 2020-2022 RS is the only Street Triple in the generation with a 5-inch TFT. The R model makes do with an analogue/digital unit (which I prefer!).

2023+ 5th Generation Triumph Street Triple Range

2023 Triumph Street Triple Model Range

In November 2022, Triumph updated its Street Triple range with significant upgrades for the 2023 model year.

Upgrades across the line include:

  • Cornering ABS and Traction Control, thanks to an integrated IMU (Inertial Measurement Unit) — This is somewhat rare in the middleweight class (though the Yamaha MT-09 has had it since 2021)
  • Higher-spec brakes on the premium models — Brembo Stylema, an upgrade from Brembo M50
  • Enhanced TFT instruments across the range
  • A new limited-edition Moto2™ range

See other motorcycles with an IMU / Cornering ABS and TC here.

Common specs across the range are

  • The 765 cc triple engine (though with different power specs)
  • Peak torque of 80 Nm / 59 ft-lb at 9500 rpm. The higher-power RS and Moto2™ editions are just tuned for slightly more high-end power.
  • Compression ratio of 13.25, up from 12.65 in the earlier gen
  • Same frame, subframe
  • Rear brake is a 220 mm disc with Brembo single-piston caliper
  • “Optimised” Cornering ABS / TC for the whole range
  • Same 6000 mile / 10000 km and 12-months service intervals
  • Brakes are on Twin 310mm discs, and all are radial-mounted monoblock calipers
  • Suspension is fully adjustable front and rear (though of different spec)
  • Rear suspension has a piggyback reservoir, whether Showa or Öhlins.

Here’s the model-by-model, spec-by-spec breakdown.

As for options — most are available across the range. You can get a cruise control kit for the 2023-onward Street Triple RS and Moto2 (but not the R) as well as an optional accessory. The cruise control kit replaces the switch block.

One question you might have is: Where’s the Street Triple S? Where’s the A2/LAMS version? Well, my guess is that it’s going to continue as it was for the 2020-2022 edition. It won’t get higher-spec brakes, suspension, or of course power. Triumph MAY improve the instruments, or update it aesthetically, but I’m not sure yet.

2023+ Triumph Street Triple R

2023 Triumph Street Triple R Silver Ice

The base model for the 2023+ model year is the Triumph Street Triple R.

It has a slightly lower-power engine than the Street Triple RS, but unless you’re always pinning the throttle at high RPMs, the difference is a rounding error. And it has sporty but not as high-end suspension as the RS.

But the 2023 Street Triple R is probably the best bike for 95% of Striple riders.

Basically, the acid test questions I would ask myself when deciding between the two are:

  • “Am I inevitably going to update the rear shock to the same Öhlins unit?”
  • “Do I really want that fancier display with its track-focused features?”
  • “The literal acid test: Do I want it in ‘Cosmic Yellow’?”

If your answer is “yes” to all three, then you might actually want the RS!

I admit that I’m a sucker for yellow (though not acid yellow). OK, personal feelings aside, here are the facts.

With the 2023 RS, Triumph has given the motor a slight power bump (7 kW / 10 bhp or PS), an Öhlins rear shock, a TFT panel, and an improved Brembo front brake. There’s also a less obvious difference in the fork — the fork is a Showa BPF, but not “Separate Function” (in which each fork leg does something different; in this case they both do the same thing).

As I noted above — On an SF-BPF, you modify preload on one side, and rebound/compression damping on the other. On BPF, you modify all three things on both fork tubes.

I got to ride the 2023 Street Triple RS recently. I rented it and spent a couple of glorious days riding in the hills of Southern California. It was marvellous, a bike that totally delivered on its promise — perfect balance, wonderful engine, and very easy to ride. Read all about it here.

Finally, the limited-edition Moto2™ edition.

Like the Daytona Moto2™, the Street Triple Moto2™ is limited to 1530 units (765 of each of the two color schemes — yellow and red). It has higher-spec, making it even more track-focused than the RS, though it’s still able to be road registered of course, and equally driveable as an everyday bike if you want to.

What makes the Moto2™ model distinct is

  • Clip-on handlebars for a more aggressive riding position — but no fairing
  • Öhlins front suspension — it’s quite unusual for a Street Triple to have an Öhlins fork (even the upgraded models are usually limited to an Öhlins shock)
  • Some unusual color schemes (I’m not really a fan of acid yellow, but it seems to be trending)
  • Carbon fibre bodywork

If the Moto2™ is the one for you, you should act quickly as most dealer stock will be limited.

What’s Next for the Triumph Street Triple?

Wow, there are a LOT of models of Street Triple up there! This article is over 5000 words long and took me a long time to write.

The Triumph Street Triple isn’t going anywhere. It’s one of the most popular middleweights out there.

When I first published this guide, I had noted that there was a lot of stiff competition. The Yamaha MT-09 had been nipping at the heels of the Street Triple for years, and the Yamaha 2021 MT-09 SP, with its 6-axis IMU, standard cruise control, and a bunch of rideability improvements, lead Motorcyclist to lead with the headline “Yamaha Builds a Better Triumph”. Not pulling any punches! They’re still a strong competitor, even though Triumph has the horsepower edge.

Aprilia has a pair of middleweight sport bikes two with a raucous parallel twin (not the same to me, but some love it), and also loaded with rider aids and technology (even cruise control). They’re cheaper, too, and look fantastic.

And finally, Triumph upped the ante on itself by releasing its Speed Triple 1200 RR (one of 2022’s best-looking motorcycles, in my subjective opinion), which is like a Speed Triple 1200R but with clip-ons, a cowl, and semi-active suspension.

So all this puts a bit of pressure on Triumph’s speed triple range. I don’t foresee semi-active suspension on a middleweight in the near future.

But Triumph has responded to the market by adding an IMU to their Street Triple for the 2023 model year, at last. But they still don’t have cruise control as standard — not really necessary unless you live in a place with lots of speed cameras around school zones. If you’ve experienced what it’s like to get one of those speeding tickets, you’ll understand!

Triumph’s Moto2™ version looks enticing, but it’ll be rare as anything. And I’d still welcome one styled like the 1200 RR.

This doesn’t mean I want any of that, of course — just that it’s the direction in which I see it going. My personal pick — if you want a bike that’s the sweet spot of everything, then get a 2020-2022 Triumph Street Triple R. It’s enough bike to keep you entertained for a lifetime. But I could say that about any of the Striples.

  1. Hey Dana
    Great overview. Noted a few details which are different though.

    The first R had fully adjustable shocks; front AND rear.

    The Rx hat the tail section taken straight from the Daytona.

    Best regards

  2. If I had the option and budget I would say the 2017-2019 R us hands down the best bang for your buck unless you really want the analog tac. If they ever make it more reliable pretty sure those year of R can be upgraded with the Triumph GPS and Blue Tooth module since it’s the same TFT.

    I went for a 21 RS myself got way too good of a deal and couldn’t find a 2017-19 R for the life of me.
