The new Aprilia RSV4 is the facelift to the 2014 machine and has been given cosmetic and mechanical updates to compete with the new generation of litre-class superbikes that were unveiled at the 2014 EICMA motorcycle show.
In terms of design the 2015 Aprilia RSV4 RR looks similar to its predecessor but the Italian manufacturer claims that the front portion of the bike has been redesigned from the ground up.
The front fairing has been aerodynamically honed to offer better wind protection whereas LED lights make their appearance felt on the headlamp and turn indicators.
Powering the 2015 Aprilia RSV4 RR is the 999cc, V4 motor as seen on the older bike, but the powerplant has been tuned to extract 202PS and peak torque rating of 115Nm at 10,500rpm. The new mill generates a healthy 16PS more than its predecessor.
The new RSV4 is also lighter by over 1.5 kg than its predecessor. Aprilia says the power gains come from reducing internal frictions, improving combustion efficiency, and fluid dynamic efficiencies. These changes allow the RSV4 RR to rev higher than before, and thus make more power.
The airbox has been redesigned, and the bike gets new fuel injectors, and the variable air ducts have been given a greater range of motion. Aprilia’s advanced electronics package, APRC, has also been updated for 2015 into a second-generation system. Titanium valves, lighter con-rods, new gear ratios, and a new exhaust system complete the mechanical changes.
