Extrema makeover: Aprilia put the RS660 on a diet for a limited-edition focused model

Aprilia have revealed a lighter, carbon equipped version of their RS660 sportsbike with a claimed kerb weight of just 166kg at this year’s Eicma show.

Called the RS660 Extrema, the Noale firm have shed the extra pounds via an all new, street-legal exhaust system by Italian specialists SC Project.

Also helping the bike reach an impressive claimed 100bhp, it features a carbon silencer positioned on the righthand side, a change from the twin-exit under engine design of the RS. 

The silencer is held by a black anodised aluminium bracket, which allows the removal of the passenger foot pegs and thus more weight saving.

Although able to carry a pillion, the Extrema comes with a single-seat tail fairing, replacing the passenger seat which is supplied separately.

Trackday focus is heightened too with software that allows the gearbox to be set up in race shift, without replacing any bike components.

All other rider aids are carried over from the existing RS model and include the usual array of adjustable lean sensitive gadgets, such as traction control, cornering ABS, engine braking, engine maps and wheelie control.

Also shedding weight is a carbon front mudguard and a newly designed belly pan, with the bike finished in a striking white and red livery.

No pricing was available at the time of writing.
