The Aprilia RS 660, launched for the 2020 model year, revived the middleweight sportbike category just as it was fading. Its 659 cc parallel-twin uses a 270-degree crank for a V-twin-like exhaust note and pulls roughly 100 hp at the rear wheel. Around 183 kg ready to ride, the bike pairs an Italian-feel aluminium chassis with a complete electronics suite: ride modes, traction control, wheelie control and a quickshifter, technology Aprilia previously reserved for its V4 superbikes.
The RS 660 targets riders who want sportbike styling and trackday capability without the wrist-on-tank ergonomics of a litre superbike. It is friendly enough for daily commuting, fits A2 licence holders via the Trofeo restrictor kit, and is a natural step up from a 125 or naked middleweight. Direct rivals include the Yamaha R7, Kawasaki Ninja 650 and Suzuki GSX-8R, but the RS 660 stands out with its premium electronics package and lightweight Italian chassis.
Early 2020-2021 units had a notably abrupt low-speed throttle response - confirm the dealer software update has been applied.
Check the quickshifter for hesitation or missed shifts; some owners report early shift-sensor wear.
Look for hot-start fuelling glitches; the mapping is sensitive to poor-quality fuel and dirty injectors.
Inspect the fairing edges and front cowl for stone-chips and stress cracks around the mounting tabs.
Ask whether air filter and coolant have been changed on schedule - both are awkward to access on this compact chassis.
