This is the maintenance schedule for the 2020+ Aprilia Tuono 660, Aprilia’s entrance into the “middleweight naked” category.
The Aprilia Tuono 660 uses an all-new 659cc liquid-cooled DOHC parallel twin engine with a 270/450-degree firing order, giving it a nicely aggressive rasp off idle. It’s the same bike as used in the previously-announced Aprilia RS 660.
The Aprilia Tuono 660 is a high-end middleweight standard sportsbike. With premium features like fully adjustable front suspension (and rear suspension adjustable for preload and rebound damping), cornering ABS, and cruise control, it offers a lot in a package which doesn’t require you to go to ride it to the extreme to enjoy it.
Its modest (but fun) 75 kW / 100 hp engine produces peak power at 10,500 rpm and peak torque at 8,500 rpm in stock trim. Those figures are both low enough and low enough in the rev range to mean that this bike is very street-usable.

Maintenance schedule for the Aprilia Tuono 660
Below is the maintenance schedule from the Aprilia Tuono 660’s service manual.
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.

General info about the Aprilia Tuono 660
The Aprilia Tuono 660 is a refreshing but somewhat expensive entrant into the middleweight standard/sports segment, released and made available in 2021.
It’s a competitor to other high-spec, mid-weight standard/sport bikes like the KTM 890 Duke R and the Triumph Street Triple RS.
The Tuono 660’s 75 kW / 100 hp motor, while “middleweight”, is very well-matched with the motorcycle’s low weight of 183kg — wet, with a full tank of gas. It’s a very lightweight motorcycle, especially considering the high level of spec.
The Aprilia Tuono 660 can be seen as a somewhat “stripped back” version of the RS 660. Despite this, the two motorcycles are the same weight — so really, the Tuono 660 can be seen as the same bike but in a different configuration.
The Tuono 660’s engine has an aggressive 13.5:1 compression ratio. This both helps the engine achieve higher peak power, as well as keep it very efficient, for maximum combustion, for Euro 5 compliance.
To keep the engine cool with that high compression ratio 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).
The Aprilia Tuono 660 can also be seen as a little brother of the bigger Aprilia Tuono V4. The 2021 incarnation of the Tuono V4 has a 1077cc 65-degree V4 engine that produces 129 kW (175 hp) peak — all specs around 50% more than the little Tuono 660. However the V4 only weighs about 15% more at 209 kg wet, so the power to weight ratio of the bigger bike is better.
Even though the Tuono 660 has a “smaller” engine, it’s hardly a sleeper. In fact, Aprilia’s premium paint colour is “Acid Yellow”. It’s pretty striking!
The comfortable seating position of the Tuono 660, compared to most sport bikes including its stablemate the RS 660, means you can ride the Tuono for much longer in the day.
The Tuono 660 distinguishes itself from middleweight Japanese bikes by its high-end running gear. Its Kayaba fully adjustable forks and Brembo brakes on 320mm discs are the kind of equipment you might see on motorcycles with 50% more engine capacity peak power.
And the Tuono 660 distinguishes itself from its European brethren with its high technology. Its competitors tend to have some of these features, but none of them has all the tech that the Tuono boasts.
Some of the tech that makes the Aprilia Tuono 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
Basically, while a naked bike, the Aprilia Tuono 660 is a premium naked bike. Many of those features are the kind of gear you might more often see on a high-end BMW or Honda touring rig.
In July 2021, Aprilia announced that many Tuono 660s had been plagued with a “con rod” issue — a connecting rod in the engine tends to crack under pressure. If your engine is affected by this, they’ll replace the whole engine for free.
