About the Aprilia Tuono V4 (2011-2024)
The Tuono V4 is an RSV4 superbike with the fairing stripped off and the bars raised, which is why it works. Aprilia launched it in 2011 with the 65-degree V4 from its World Superbike winner, grew it to 1,077 cc in 2015, and kept sharpening it for a decade. Nothing else in the class sounds like it.
The appeal is superbike hardware under an upright riding position: the RSV4's aluminium twin-spar frame, and APRC electronics (traction, wheelie and launch control) that arrived years before rivals had them. ABS became standard in 2014, and Factory versions add Ohlins suspension, semi-active from 2019, so where a bike sits in that timeline matters.

Known issues to check before you buy
- Cam chain tensioner. Pre-2016 bikes rattle on start-up because the tensioner drains of oil while parked; a 2016 non-return oilway fixed it. Rattle that does not clear means replacement, and V4 internal damage is expensive.
- Stator and voltage regulator. A known weakness of this era: strong flywheel magnets drive a hot, high output stator that burns its windings and often kills the regulator. Check charging voltage.
- Fork seals. The Sachs forks on standard models pop seals regularly. Bounce the front end and look for oil on the sliders. Factory models run Ohlins.
- Gearbox and quickshifter. Some bikes show gear wear traced to the factory quickshifter, so ride through every gear under load. The cassette design makes repair quicker.
- Valve clearances. Due every 12,500 miles or 24 months, and a serious labour job on a V4. Ask for paperwork proving it was done.
- Heat, electrics and finish. Early dashes mist up from water ingress, a sticking exhaust valve sets warning lights, and it runs hot in traffic. Check fasteners for corrosion.
