The MotoSport.com Rizoma 3D Brake / Clutch Lever Combo includes ONE Rizoma 3D Brake Lever and ONE Rizoma 3D Clutch Lever, both with the following features: Rizoma 3D Brake / Clutch Lever: Aerodynamics and grip - The 3D levers were developed through in-depth wind tunnel testing and analysis. When used at high speeds (e.g. on racetracks), the resulting air pressure can have a significant impact on the braking circuit. To reduce this effect the outer tip of the lever has been hollowed to minimize this pressure and optimize performance. Made of anodized billet aluminum, these levers provide plenty of scope for adjustment as they move on bushings with return springs, ensuring precision and reliability. Moreover, in the event of a fall, the articulated joint lets the lever 'fold', reducing the likelihood of breakage. Surface machining ensures enhanced grip.
