Aprilia’s RS 660 dominated MotoAmerica’s Twin Cup 2021, and the brass in Noale are so proud of it that they’re celebrating the championship by issuing a limited-edition model. This special 1,500-unit run is clearly identified by special graphics inspired by Old Glory.
On the technical side, the bike receives a larger fairing for better aerodynamics, a single seat with a racing-style cowl, and a special version of Aprilia’s quickshifter allowing riders to easily set the shifting sequence according to their preference; no special parts are needed to go from standard to GP shift.
More substantial is the upgraded 660 Tuono in its new Factory Edition guise. The engine remains unchanged, with a claimed 100 hp and 42 pound-feet of torque, but the bike’s already excellent chassis has been further refined. At the front there’s now a 41mm Kayaba fork, fully adjustable for compression, rebound, and preload. The same goes for the new Sachs rear shock absorber, which features a separate reservoir of compressed nitrogen.
A lithium-ion battery replaces the standard lead-acid unit, saving 4.4 pounds to further enhance the little Tuono’s power-to-weight ratio. A 16-tooth front sprocket (one less than the standard Tuono) means a livelier final ratio and enhanced response from the 270-degree parallel twin.
The electronic suite is one of the most advanced in its class, using an as-standard six-axis inertial platform (a $200 option on the base Tuono 660) managing all major riding and safety functions, including cornering ABS; traction control; wheelie control; and five riding modes, three for the road and two for the track. Adaptive LED headlights, which Aprila calls Bending Lights, add a final high-end touch and make for safer night riding.
Pricing and availability of both models will be announced at a later date.
