100hp, 169kg Aprilia RS 660 sportsbike reveals its finer details ahead of launch

The Aprilia RS 660 reveals its full specifications and features ahead of its long awaited and much anticipated press launch in Italy this weekend

Full details and specifications for the much anticipated new Aprilia RS 660 sportsbike have been revealed ahead of its official global launch this weekend as the Italian marque launches the first model from its new middleweight platform.

Revealed in concept form at EICMA in 2018, followed by the production version a year later in 2019, the Aprilia RS 660 will finally fall into our hands this weekend as we gear up to find out whether the fresh twin-cylinder has what it takes to carve a little niche out for itself in the sportsbike market.

Aprilia RS 660 - All you need to know about the all-new sportsbike

Borrowing styling cues from the established RSV4 1100 at the top of the range, the RS 660 updates the signature look with a triple LED headlight assembly, daytime running lights and flanked by a double fairing with integrated aerodynamic features to both trim weight and drag.

Indeed, by boasting 100hp @ 10,500rpm but only tipping the scales at 169kg (dry) the RS 660 punches above its weight with its forward-facing parallel twin, four-stroke engine, plus 67Nm torque @ 8,500rpm. The RS 660 can also be adjusted down to meet A2 licence compliance.

While you’ll need to wait a little longer to find out how it performs on the open road when we take to the roads of Noale, Aprilia confirms traction, wheelie and cruise control and a total of five riding modes -  three for the road and also two more specific to track day usage.

Commute (everyday riding), Dynamic (sports riding) and Individual (customised settings) are designed for common use, with Challenge (on-track racing sessions) and Time Attack (settings experienced riders to tweak for optimum performance) are aimed purely at the purist racer.

With ‘lightness’ and ‘compactness’ terms being sprinkled liberally across the press pack, it’s clear the Aprilia RS 660 is a honed race bike for the road and nestles neatly between the RS 125 and RSV4 for featherweight B-road thrills. 

Aprilia says the decision to “take advantage of the V4 technology guarantees top-class performance, while taking into consideration the high piston stroke speeds relative to its displacement size”.

The Aprilia RS 660 is well kitted out too with class-leading electronics designed to amplify the fun while keeping you sunny side up, including a six-axis inertial platform, which uses data from the rider to adjust the characteristics of the bike. 

It allows for necessities, like the licence plate holder and wing mirrors, to be removed when taking the RS 660 out on a track day. 

The launch has also allowed the unveiling of a new Acid Gold, to go with the Lava Red and Apex Black that were presented during last year’s world premiere.

The Aprilia RS is the first model to be launched on the all-new 659cc platform, which is set to also spawn a Tuono naked variant, a Tuareg adventurer and an RS Trofeo honed sportsbike for proper track day use.

Prices are due to begin at £10,149 with order books opening imminently.
