It offers up wildly impressive numbers for a small parallel two-cylinder engine. The Aprilia RS 660 is powered by a compact 659 cc four-stroke parallel 270-degree twin producing a claimed 100 horsepower at 10500 rpm and 49.5 ft/lbs of torque at 8500 rpm. It has been very well receivedĪprilia’s new RS 660 is probably the sportiest of those except maybe for the R7 but still falls in line with the ethos of a sporty motorcycle that lives comfortably on the road and the track.īeing arguably the sportier of the bunch in the loosely defined class, the RS 660 has its work cut out as is also compared to the Ducati Supersport 950, V2 and other Supersport 600s so it has the knives coming in from all anglesĪprilia RS 660 Dyno Curve & Engine Performance
Just recently, Yamaha have expanded upon the MT-07 and have introduced the YZF-R7 which is based upon the MT-07 but wrapped in a more sport full faired design.
Manufacturers have been more focused offering sporty looking faired and naked motorcycles that are less extreme but offer good real-world performance with models such as the Ninja 650, MT-07 and Honda’s CBR650R and more recently the RS 660. We could argue that it is because the extremely focused Supersports market has been in some decline for many years. Many of us have hoped for Aprilia to enter the Supersport market but they have resisted doing so for a good while until now. Aprilia are not hugely prolific with introducing new sport motorcycles, rather choosing to revise and perfect existing models such as the brilliant RSV4.
