Details of the Aprilia RSV4 RR have finally surfaced, and it seems the folks at Noale have not been resting on their laurels, having just won the 2014 World Superbike Championship. As such, the 2015 Aprilia RSV4 RR makes a cool 201hp from its 999cc V4 engine, with peak torque coming in at 84.81 lbs•ft at 10,500 rpm.
Not only does the 2015 Aprilia RSV4 RR make 16hp more than its predecessor, but it’s also three pounds lighter (1.5kg). 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.
