Product Overview

Restore the smooth, responsive acceleration of your scooter with the Mitsuboshi CVT Drive Belt (18.3x775-30). This premium Japanese-engineered belt is the gold standard for high-performance transmission components, offering superior grip and thermal stability compared to generic aftermarket alternatives.
