This is the maintenance schedule for the 2022+ Aprilia Tuareg 660, Aprilia’s middleweight adventure bike.
The Aprilia Tuareg 660 uses a 659cc liquid-cooled DOHC parallel twin engine with a 270/450-degree firing order, giving it a bit of bark off idle. It’s the same engine as used in the Aprilia RS 660, but tuned more for mid-range torque rather than top-end power. It still makes a respectable 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.
Nonetheless, the core maintenance schedule is the same as for its siblings and many parts are shared.

Tuareg 660 — Pre-ride checks
A number of things are mentioned in the service schedule that are really pre-ride checks you should do before every ride (or every day if you ride it every day).
Aside from the first few items, you check most controls and moving parts of the bike by inspecting them as you pull away.
|Aprilia Tuareg 660 Pre-ride 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|
Maintenance schedule for the Aprilia Tuareg 660
Below is the maintenance schedule for the Aprilia Tuareg 660.
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.
Generally speaking, the Tuareg 660 has 10000 km (6200 mi) service intervals at which you have to change the oil, lubricate some parts, and check a bunch of things. Every two services (20000 km / 12400 mi) you check the valve clearances and change the spark plugs.

Chain maintenance on the Aprilia Tuareg 660
Check and clean, adjust, or replace the Tuareg 660’s chain if necessary 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. Tuono recommends you halve the maintenance intervals if riding your bike off-road.

About the Aprilia Tuareg 660
The Aprilia Tuareg 660 is a Aprilia’s entrant into the super hot “light middleweight” adventure bike market. There have been middleweight adventure bikes for a long time (e.g. the KLR650, which also has been reinvigorated with fuel injection), but there have been a recent crop of decent-performance ones from a number of manufacturers.
The Aprilia Tuareg 660 is based on the same engine platform as the other 660 bikes from Aprilia, including the Aprilia Tuono 660. The base engine is 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 10%. The goal of this is for more midrange torque. They did this by changing the camshaft lift, increasing the length of the intake ducts and changing the filter casing to facilitate removing the air filter. They 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 (to be honest their torque curves aren’t that aggressive either), just not quite as optimised for it.
Aprilia also changed the gearing on the Tuono 660. 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 — and one would wonder why you would… it’s not exactly made for rock-hopping.
The Aprilia Tuareg 660, being a dual-sport adventure motorcycle, has a very different suspension and wheel setup to its 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 wheel travel of 240mm. The rear fully adjustable Kayaba monoshock also gives the wheel 240mm of travel.
And the wheels are a traditional spoked 21/18 adventure bike setup, but with tubeless tyres. Hooray!
To keep the 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 bike include
- Cornering ABS and lean angle-aware traction control, via an IMU
- Ride modes (five of them!)
- A quickshifter
- Cornering lights
- Automatic high beams
- Self-cancelling turn signals
- Full LED lighting
- A colour TFT display
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 Kawasaki KLR650.
