Aprilia RS660 Extrema details 2023

It was always a question of ‘when’ and not ‘if’ that Aprilia would deliver an ever sportier version of their sporty RS660 and by doing so the Noale brand has resurrected the ‘Extrema’ tag that will make some reminisce about pubescent days of ragging a two-stroke RS125 around their local streets. Good times…

So just how extreme is the Extrema?

What is the Aprilia RS660 Extrema?

Aprilia’s RS660 proved to be a hit for those who wanted supersports performance and looks without huge amounts of horsepower, MotoGP electronics and an eye-watering price tag. But for those who want a bit more bragging rights, the Extrema is their answer.

What is the difference between the Aprilia RS660 Extrema and base model?

The first thing to notice is the snazzy paint job that is exclusive to the Extrema (and a darn site nicer than the Limited Edition Stars and Stripes version used to celebrate the bike’s victory in the US Twin Cup series).

The Extrema also shares the Limited Edition’s up and down quickshifter and single seat unit (although a passenger seat does come with the bike). The street-legal SC Project exhaust with carbon silencer marks a big change from the standard bike as it exits from the right side of the bike as opposed to being under the engine. It also comes with the black anodised aluminium silencer bracket which allows you to remove the passenger footpegs, leading to even lighter weight.

The mudguard and bellypan are also a new design and made from light and strong carbon fibre.

Aprilia RS660 Extrema weight

The Extrema shaves 3kg of weight off thanks to the refined and new standard equipment to further improve the power (100hp) to weight ratio, which Aprilia already claims a best figure in class for.

Aprilia RS660 Extrema Engine and Performance

Aprilia isn't claiming any additional power from the 659cc parallel twin cylinder at 100hp, but the drop of 3kg (combined with having a big poo) will help it accelerate quicker than the base model away from the traffic lights.

Aprilia RS660 Extrema Price

The base model starts at £10,300 and the Limited Edition at £10,600 (although Wheels Motorcycles in Peterborough have some great deals on), but with no official price as yet (November 2022) we expect the Extrema to come in closer to £11,200.

Aprilia RS660 Extrema colours

There is just the one for the Extrema - red and white.

Aprilia RS660 Extrema technology and rider aids

The bike features a 6-axis IMU with the APRC suite that includes ATC (traction control), AWC (wheelie control), AEB (engine brake) AEM (engine mapping), ACC (cruise control)

5 riding modes (Road and Track, 3 pre-set and 2 customisable). For track fans, the RS 660 Extrema also has software that allows set up of the quickshift in upside-down configuration. This means that the gearbox can be configured completely autonomously, without replacing any bike component, in street or race version.

Aprilia RS660 Extrema aerodynamics and bodywork

We can’t tell if it has the same larger upper fairing profile from the Limited Edition, but it does have a carbon fibre mudguard and bellypan. There’s also a cover for the passenger seat to give it a single seat race look.
