2023 Aprilia RS660 Extrema First Look

The RS660 goes on a diet thanks to SC Project and some carbon fiber.

Aprilia is celebrating the success of the RS660 worldwide (and claiming it’s the best-selling sportbike in Europe) with this – the RS660 Extrema, the sportiest version of the RS660 family. The name is modeled after that of the Aprilia 125 Extrema, one of the highest-performing and fastest eighth-liter bikes ever, manufactured from 1992 to 1994.

The highlight feature of the Extrema is the SC Project exhaust system, which now exits on the right side of the bike instead of underneath it on the standard RS660. A black aluminum anodized exhaust bracket replaces the stock passenger pegs, thus saving weight. Further weight reduction comes from the carbon fiber front fender and bellypan. The single-seat tail fairing replaces the passenger seat (which, when shaped like that, probably doesn’t see much use anyway). When all is said and done, Aprilia says the RS660 Extrema tips the scales at 366 lbs (166 kg).

In addition to the standard electronics on the RS 660 (which include traction control, cornering ABS, engine brake, engine map, and wheelie control – all adjustable) the RS660 Extrema also has software that allows you to set up the quickshifter in upside-down, or reverse shift, configuration. This means that the gearbox can be configured completely autonomously, without replacing any bike components, in street or race version – ideal for track days. The new dedicated white and red livery is clearly sport-inspired and contributes to making it recognizable at a glance.
