Minarelli 50cc 788-17-28 Premium CVT Drive Belt

Minarelli 50cc 788-17-28 CVT Drive Belt for 2-Stroke Engines

The 788-17-28 CVT drive belt is built for 50cc 2-stroke Minarelli engines, where it carries power through the variator and keeps top-end performance consistent. It is designed to handle the repeated heat cycles that CVT systems produce. As part of our Minarelli 50cc and Yamaha Jog scooter range, it suits routine servicing as well as tuning work. Made in Japan to OEM specifications, it offers the durability and accuracy needed for steady running across different riding conditions.

Construction and Design

The belt uses high-modulus aramid fiber reinforcement to resist stretching and breaking under strong heat. Its precision groove profile, cut at a 28-degree angle, seats correctly in the transmission and rear pulley, helping the belt transfer torque efficiently.

Installation Tips

Before fitting a new belt, wipe the variator and clutch pulley faces clean with brake cleaner. This removes leftover rubber from the old belt and reduces the chance of early slipping and wear on the new one. A careful fitting will help the belt perform reliably once you are riding.
