Braking SK3 Wave Floating Rotor Ø320 Right BMW S1000RR/R/XR

Braking WK3109R disc brake floating with diameter 320mm model SK3, with a Wave design.
 
The induction hardened stainless steel braking band offers superior strength and durability, while the hard anodized AL6061 aluminum directional hub (30μm) adds a touch of elegance and reduces overall weight for superior handling.
 
Thanks to the non-round design of the outer and inner diameter of the disc, the Braking SK3 allows for better radial expansion of the rotor even in the most extreme heat conditions. The edges replace the perforation holes, specifically designed to optimize the brake pad regeneration process.
The patented double-curved grooves are the response to the periodicity of vibrations, reducing the amplitude of the noise for a quieter and more comfortable ride. The directional pawl seat with a 14° angle adds precision to braking, ensuring greater grip, high reactivity and constant power in all conditions.
