Aprilia's 2018 RSV4-RF is areal jewel, with 215bhp, a new electronics package, loads of carbon and a full racing exhaust system.
Those new features have been totally overshadowed by the addition of wings. WINGS!
Yes, their aerodynamic prowess may be questionable, but it's the first production bike (short of the Kawasaki H2) to sport the technological feature that's trickled down from their MotoGP bikes. The MotoGP guys have been taking aerodynamics very seriously the last few years, with various incarnations being developed and subsequently banned by DORNA.
Aprilia will also sell you their track only 250bhp monster, if you can afford it
