Aprilia RS 660: any differences from the Concept and an engine close to 100 horsepower?

At last year's edition of EICMA, RS 660 Concept di Aprilia aroused some interest. A purely sporty setting and a twin-cylinder heart derived from the heart of the powerful one RSV4 have caught the attention of professionals and enthusiasts. Considering the most recent rumors and several registered technical drawings that have appeared on the web, a potential production version would not be too different from the prototype. In any case, at the moment the conditional is a must.

Less than 100 horsepower, even in the detuned version?

In the drawings filed, the frontal area, in particular the faired one, seems slightly more articulated and exposed than the prototype admired at EICMA last November. Some elements such as arrows and mirrors may have a more traditional location than what is noted on the RS 660 Concept. The proposed vision appears muscular and would also allow a look towards the underlying elements, while the rear area roughly follows that of the prototype, although certain differences emerge in the setting of the swingarm and exhaust, without the presence of linkages in the suspension area, based on what perceived.
The stressed element is linked to aluminum frame it would be the engine. An inline twin, probably from 660 cc, related to the unit present on the powerful ones Thunder e RSV4 di Aprilia. A boost is expected close to 100 horsepower, among the hypotheses there could also be 95 thinking about a possible weakened by 35 kW aimed at license holders A2. The motorbike could be equipped with instruments TFT and a front fork is also hypothesized Sachs with stems from 43 millimeters, compared to a solution Öhlins noted on the Concept. In any case, a sporty but also functional piece of equipment, to facilitate variable and manageable use.
Another interesting question, in view of the ad appointment EICMA scheduled from 5 al 10th November 2019 at the pavilions of Rho Fiera Milano, is the proposed regulation Euro 5 regarding emissions. A topic related to the new production.
