Not too powerful, not too weak. Not light, but not heavy. Not a show-winner, but not ugly. And not a dirt bike, but not incapable off-road. The Aprilia Tuareg 660 is Aprilia’s attempt at trying to placate everyone, and make a bike that can go anywhere. And it isn’t half bad.

Below is a host of information about the Tuareg 660 that might be useful for prospective buyers (including myself), including an overview of the bike, controls, maintenance information, and more.

The Aprilia Tuareg 660 uses a 659cc liquid-cooled DOHC parallel twin engine with a 270/450-degree firing order. It’s a tried-and-true format, with the same basic engine used in the Aprilia RS 660, but tuned more for mid-range torque rather than top-end power.

Despite de-tuning, the Tuareg 660’s engine still makes a respectable (for its capacity) 80 hp (59 kW) at 9250 rpm, with torque arriving lower than on its siblings, with 52 ft-lb (70 Nm) peaking at 6500 rpm.

The Tuareg 660 is quite different to its siblings the RS 660 and Tuono 660 — more than just in engine tuning and riding position. The frame is designed to carry heavier loads and withstand larger shocks, the suspension is longer travel, and the wheels are off-road sized with a 21-inch front wheel.

About the Aprilia Tuareg 660

The Aprilia Tuareg 660 is Aprilia’s entrant into the thriving “middleweight” adventure motorcycle market. There have been middleweight adventure bikes for a long time (once upon a time, all bikes were what we’d now consider to be “middleweight”), but for a while, they were outclassed by bigger ones. Recently, though, there has been a crop of high-spec middleweights from a number of manufacturers.

The Aprilia Tuareg 660 is based on the same engine platform as the other 660 bikes from Aprilia, the Aprilia RS 660 and Tuono 660. It’s the “same platform” in that it has the same bore, stroke, and displacement. It’s a 659 cc liquid-cooled parallel twin with four valves per cylinder and dual overhead camshafts.

But there’s quite a bit that’s different about the Tuareg compared to the Tuono and RS — this isn’t just a re-skinning exercise.

For starters, the engine in the Tuareg 660 has been retuned, with a drop in peak power of around 20% vis-a-vis the Tuono or RS. The goal of this is for more midrange torque. Aprilia achieved this not just by applying a tune, but also by changing the camshaft lift, increasing the length of the intake ducts and changing the filter casing to facilitate removing the air filter. Aprilia also adjusted the exhaust system for low-rpm response. All this was of course done with an engine map to suit.

The result of those adjustments is that the Aprilia Tuareg 660 reaches peak torque of 52 ft-lb (70 Nm) at just 6500 rpm, with 75% of that peak being available at 3000 rpm and 85% at 4500 rpm. The Tuono / RS 660, by contrast, make a little less torque (49 ft-lb / 67 Nm), and higher up in the rev range (8500 rpm). But they’re not short on low-end torque, just not quite as optimised for it.

Despite the detuning, the Tuareg 660’s motor still has a high 13.5:1 compression ratio. It still needs premium fuel! As far as I can tell, there’s no anti-knock sensor to retard ignition in case of low-grade fuel. However, the manual doesn’t warn against low-grade fuel, while it does warn against ethanol content of over 10%.

Aprilia also changed the gearing on the Tuareg 660 vis-a-vis the Tuono / RS. They shortened the first gear ratio, and changed the front sprocket to a 15-tooth one from 17 as on the other 660 bikes. The goal of both these was to increase low-speed control and to maximise throttle response.

Even if you changed the gearing on a Tuono 660 for example, it’d be a lot harder to change the first gear ratio for the purpose of off-road adventure riding at low speeds.

The Aprilia Tuareg 660, being a dual-sport adventure motorcycle, has a very different suspension and wheel setup to its sportier siblings.

The front suspension is a Kayaba 43mm upside-down fork that’s fully adjustable. That much is to be expected, but it also has a rather generous suspension travel of 240mm. The rear fully adjustable Kayaba monoshock also gives the rear wheel 240mm of travel.

And the wheels are a traditional spoked 21/18 adventure bike setup, but with tubeless tyres. No prying off tires in the middle of nowhere to patch a tube. Hooray! (But also, that can help sometimes, if you really ding up your rim…)

While the frame is designed to carry heavier loads, the Aprilia Tuareg 660’s subframe is welded to the main frame, rather than attached as a separate part. This means that crashes that ding up the subframe would risk writing off the motorcycle, which would be unnecessary on a motorcycle where it were replaceable.

To keep Aprilia Tuareg 660’s engine cool with its high compression ratio of 13.5:1, there’s both a radiator AND a water-oil heat exchanger, interestingly (other motorcycles tend to skip on the latter, or to use a separate oil radiator).

Some of the tech that makes the Aprilia Tuareg 660 usable as an everyday motorcycle include

  • Ride modes
  • A quickshifter (optional)
  • Cornering lights
  • Automatic high beams
  • Self-cancelling turn signals
  • Full LED lighting
  • A colour TFT display

However, the Tuareg 660 lacks an IMU, so there’s no cornering ABS or TC. This is not a huge deal for a middleweight, but it’s an active omission, given that both the Tuono 660 and RS 660 have it (it’s optional on the Tuono).

Given that the Tuareg 660 is not cheap despite its capacity, it does give buyers pause and wonder whether they should go for a more premium alternative like the Ducati DesertX. (Of course, more goes into choosing an adventure motorcycle than simply what’s the “most premium”.)

See here for a list of motorcycles with an IMU and cornering ABS.

The Aprilia Tuareg 660 sets a high bar for middleweight adventure bikes. But all that comes with a price to pay — it’s roughly double what you’d pay for a budget Kawasaki KLR650.

Using the Aprilia Tuareg 660’s Screen and Controls

When assessing any motorcycle, I like to have an overview of the interface and the important controls — things like cruise control, rider aids, and adjusting rider settings.

The Tuareg 660 has a TFT display, cruise control, and an optional (and frequently chosen) quickshifter.

There are three main buttons to use to control the Tuareg 660’s options

  • The cruise control / TC button on the left handlebar
  • The ride mode switch block on the right handlebar, and
  • The menu switch block on the left handlebar

On the left handlebar, the button at the top is the cruise / TC button.

  • To turn cruise control on, push the button to the left. Then push it to the left again to set your speed. (You can only use cruise in 3rd gear or above.)
  • To turn speed up and down, bump the toggle up and down.

When cruise control is not on, that button changes your traction control settings (TC 1-4, or off). You can do this on the fly. To turn ATC off on the fly, you take it down to one, then hold the button down and it turns off on the display.

On the right hand side, the switch near your thumb area is the ride mode button. You can hit that button on the fly between off-road, individual, explore, and urban. (Off-road and individual are configurable.)

To de-activate ABS

  • Use the right button to go into off-road mode.
  • In off-road mode, hold the right button to deactivate ABS.
  • Note that ABS is re-activated every time you turn the bike off and on, and every time you change mode.

Most of the complexity of the controls are in navigating the options on the scree using the left switch cluster.

Aprilia Tuareg 660 left switch cluster
Aprilia Tuareg 660 left switch cluster

You use the control buttons on the left handlebar to scroll between items, scrolling up and down. You have to be at a stop to use the menus.

Whatever mode your screen is in, you navigate through various meter modes (Trip A / B, Heated grip info, Tire pressure info, phone, media etc.) with the right button.

To reset any item (e.g. the trip meter), you hold the left button.

To go into settings, hold the right button when at a standstill. This is where you can change the user code, the display settings, service interval, shift light, emergency brake flasher (a European requirement), and other similar settings.

To change a setting, you use the right arrow on the item you’ve highlighted.

There’s a lot more detail, but it’s probably best explained as “poke around while the bike is at a standstill”.

Aprilia Tuareg 660 Service Intervals

Below I’m including a bunch of maintenance / reference information fo the Aprilia Tuareg 660. This is useful for not just prospective buyers, but also for people renting them for a period or even those who own them.

Overall, the Aprilia Tuareg 660 has 6200 mile / 10000 km or annual service intervals at which you have to change the oil, the oil filter, and do a series of checks on the motorcycle.

The major service interval for the Tuareg 660 is every 12400 miles / 20000 km, at which point you should change the spark plugs and air filter, and inspect the valve clearances.

If you’re riding your Tuareg 660 off-road a lot (which is what it’s made for! At least partly) then you should service many things more frequently, including the chain at least, and also the air filter, oil, and components that might be degraded by dust, wet conditions, or just hard usage.

Aprilia also recommends replacing the fork oil regularly. See the maintenance schedule for more details.

Aprilia Tuareg 660 Maintenance Schedule

The below information comes from our sister website,

Below is a clarified version of the maintenance schedule from the manual.

It’s separated into

  1. A daily maintenance checklist
  2. A periodic maintenance schedule with major items like oil changes, and
  3. An annual service checklist

There are also separate sections below on chain maintenance.

Daily Inspection Checklist

This is the daily inspection checklist for the Aprilia Tuareg 660. Do this before every ride.

Many of these items you’d naturally do by starting to ride, e.g. confirming that the lights, brakes, and clutch work. But you should specifically check the fluid levels periodically.

Aprilia Tuareg 660 Pre-ride / Daily checks
Brake discs & brake pads (front and rear) — Check wear
Tyres – Check pressure/wear. Remove any foreign objects from treads.
Engine oil — Check and/or top-up.
Controls (throttle, brake lever, clutch lever) — Check that they function correctly
Steering — Check that the steering turns freely and is smooth with no play or slackening
Side stand — Check that it snaps back into position smoothly
Fuel tank — Check level, and check circuit for leaks
All lights and switches — check function

Major Items Maintenance Schedule

Below is the service schedule of major items for the Aprilia Tuareg 660.


  • Observe the earlier of time-based or distance-based service intervals.
  • Keep following it in the pattern shown beyond the end of the maintenance schedule.
  • If you ride your motorcycle aggressively or in untoward conditions (e.g. off-road or in mud, rain, or on dirty roads, in stop-start traffic, or in cold weather without giving it time to warm up), you may have to service your bike more often.

The service manual has the items in an unintuitive order. The order below makes more sense intuitively, e.g. with things grouped together, and “things to replace” more up the top.

Aprilia Tuareg 660 Drive Train Maintenance

Check and clean, adjust, or replace (if necessary) the Tuareg 660’s chain, every 1000 km (600 mi).

Service the chain more often if riding it in the wet, in dirt, or off-road — i.e. if you’re using the Tuareg 660 as an adventure bike. Aprilia recommends you halve the maintenance intervals if riding your bike off-road.

To measure the chain slack of the Tuareg 660, measure the total vertical deflection of the bottom section of the chain, from 320mm / 12.6 inches from the centre of the rear axle.

Aprilia Tuareg 660 Target Chain Slack: 48 mm (1.89 inches)

Aprilia recommends that you take the motorcycle to the dealer to adjust the chain, but it’s something that any competent home mechanic can do. To adjust the clearance, follow this procedure:

  1. Loosen the rear axle and the lock nuts. (For the axle you need a 26mm socket)
  2. Adjust the lock nuts evenly (paying attention to the markers) until the target chain slack is met.
  3. Tighten the lock nuts (moderately tight) and the axle nuts (120 Nm / 88 lb-ft)

Tire Sizes and Pressures

Below are the rim and tire sizes, as well as recommended tire pressures for the Tuareg 660.

The Tuareg 660 runs an adventure-ready 21-18 front-rear tire setup. Note that the tires are tubeless.
