Second generation Aprilia RS660 gets more power and tech, spikey Factory model also revealed

The traditionally focussed supersport class may be back in full swing, but that hasn’t stopped Aprilia from heavily updating their slightly softer parallel twin RS660 sportsbike for 2025. Plus, they’ve introduced a sharper Factory option at the same time.

Building on the already competent package, which scooped MCN’s Bike of the Year award in its debut year, the 2025 RS family is immediately recognisable thanks to its new fairing design – said to be inspired by the RS-GP MotoGP racer.

Unlike before, there’s now a large wing under the screen to aid with stability – developed with a use of wind tunnel time, road and track miles, plus Computational Fluid Dynamics (CFD) computer software.

New looks for the RS660

Integrated aero is also found in the side fairings, which could be deemed overkill given the fact that its 660cc parallel twin engine now produces a claimed 103.6bhp at the crank.

Acting as a stressed member within the chassis, the Euro5+ friendly engine also gets wider throttle bodies, up from 48mm to 52mm. The result is a power increase up from the original’s 99bhp – but still not enough to truly warrant winglets for anything other than aesthetics for many road-focussed riders.

Also keeping the performance in check is an even more advanced set of electronic aids, controlled via backlit switchgear and a new 5in colour TFT dash. This screen uses something known as optical bonding, to help reduce reflection and improve brightness.

The lean sensitive electronics package now welcomes launch control, with the bike already featuring an IMU and ride-by-wire throttle for a full suite of electronic controls, plus cruise and an up/down quickshifter.

Factory version launched

On top of the updated standard bike comes a more focussed Factory edition – an update that’s been expected since the arrival of the naked Tuono 660 Factory back in 2022.

Replacing the standard upside down KYB forks comes a set of 43mm Öhlins NIX 30 forks, plus an STX 46 shock absorber. Both items are fully adjustable, with hydraulic rebound and compression damping, plus spring preload. Setting it apart further are new graphics and a two-tone seat.

Exploring optional extras

To make your 660 your own, there’s a choice of accessories available for both sports and touring-orientated riding. This includes a single seat tail unit option, with the seating area itself redesigned to allow for more room when tucked in.
