Bonamici Folding Brake & Clutch Levers for Aprilia RS 660 motorcycles. Produced in Italy from aerospace grade Magnesium Alloy with an ergonomically correct design to fit comfortable and solid in your hand yet exceptionally light for racing (approx. 30% lighter than aluminum). Crafted to emphasize a connected feeling to the bike during cornering, shifting, and braking with an aerodynamic air-inlet flow hole that prevents activation (or drag) during high speed. Features a 90 degree upward pivoting design to resist breakage in a crash. Black Anodized (colors available).
