Braking SK2 Wave Floating Rotor Ø330 Left Aprilia RSV4/ Tuono

The WK discs are made with a directional hub 9% lighter than the previous model (SK Series), a new track geometry and with a directional pawl seat with an angle of 14 °.
Greater braking grip, less weight, better handling, high heat dissipation and constant power in all conditions are the main features of the Braking WK disc.
 
The external and internal diameter of the disc have a non-round design that allows a better radial expansion of the disc in extreme heat conditions. In addition, the lightening holes are replaced by edges designed specifically to improve the pad renewal process.
