Aprilia Tuono Buying Tips
The Tuono generally attracts enthusiasts who tend to look after their bikes well and use them just for fun. Annual mileages are normally low but still inspect anything you’re interested in very carefully.
It’s a fundamentally robust bike but needs more TLC than your average Japanese machine. Tuonos can do up to 100,000 miles reliably if cared for and problems are usually rare and minor but there’s potential for quite a few to crop up.
Don’t be tempted to skip services and be aware that working on the bike at home isn’t always straightforward — special tools and experience are necessary for some jobs. Regular oil changes are a must but be careful — the dry sump system means you should measure the exact amount of oil into the engine and levels should only be checked when the motor is hot. If uncertain, see a dealer. Budget for reputable dealer attention if you need to and only use experienced mechanics.
Engine reliability is generally excellent. The V-twin was well proven in the Mille sportsbike by the time the Tuono was launched. Checking the valves on the front cylinder can be tricky due to limited access and if the front cylinder’s valve cover seal isn’t seated correctly, it will leak badly. Oil pressure switches and oil filter covers can also weep oil. Clutches can drag if the fluid isn’t bled and changed regularly. Slave cylinders can leak too and they get very hot, being so close to the engine and exhaust. Aftermarket ones give a lighter and more reliable clutch action. The same is true of the rear brake slave cylinder, especially on early bikes — they are difficult to bleed. Check the pinch bolts of the Öhlins forks. If over-tightened, they can crack the legs. Oil-seal leaks aren’t unusual, particularly if the bike has been stored for a while.
