The Concept RS 660 is a possible response to the demand of new generations for fun bikes that are capable of thrilling on the road as well as on the occasional track day. The result is a product that is unique in its kind: a medium engine capacity twin-cylinder, attractive and accessible, that provides extremely high technological content, even higher than bikes in superior categories. RS 660 is a possible option for young riders coming up from smaller engine sizes, looking for a high level sport bike that can provide thrills and fun on a day to day basis on the road and ready to support the rider on the track too.
Out of the work done in the wind tunnel and from the resulting solutions, the shape of a bike was born where the lines are an absolute and direct consequence of the functions. The concept offers a comfortable riding position, thanks to the large saddle located on the sleek tail fairing, footpegs that are not too high and a pair of semi-handlebars mounted on top of the upper steering yoke.



In the concept, the frame exploits the engine as a stressed element, contributing to form a compact and stiff structure. The right arm of the swingarm has a curved shape in order to all the exhaust terminal to pass. The particular mounting of the shock absorber allows outstanding progression to be obtained without using linkage, thereby cutting down on weight and making it a cleaner package overall.
RS 660 was born around the concept of a new engine that Aprilia engineers are already working on, a 660 cc parallel twin-cylinder, a very compact new generation unit derived from the 1100 cc V4 that powers the Tuono V4 and RSV4 1100 Factory.
