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.

Designed specifically for 50cc 4-stroke engines with longer transmission cases, this belt is a direct OEM replacement for a wide range of Genuine, SYM, and Peugeot scooters. Mitsuboshi's advanced rubber compounds and high-tensile cords ensure minimal stretch and maximum durability, preventing the power loss caused by belt slippage.
