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

Description

Ensure reliable power transfer and consistent top-speed performance with the Bando Premium CVT Drive Belt (788-17-28). Manufactured in Japan to exacting OEM standards, this belt features high-modulus aramid-fiber reinforcement to resist stretching and snapping under the high-frequency heat cycles inherent in 2-stroke CVT transmissions.

The 788-17-28 specification is the industry-standard “long-belt” for the widely used 50cc 2-stroke Minarelli engine platform. Whether you are performing a routine maintenance swap or tuning a big-bore 70cc street build, Bando’s precision-molded rubber compound provides the consistent friction “bite” necessary to eliminate belt slip and keep your power delivery smooth.

Comprehensive Model Fitment Matrix

This 788-17-28 belt is the definitive fit for most 50cc 2-stroke scooters utilizing the 1PE40QMB / 1E40QMB Minarelli engine architecture.

Tuning Mechanic’s Advice: When replacing a belt, always thoroughly clean your variator and clutch pulley faces with brake cleaner to remove any leftover rubber residue from the old belt. Installing a fresh belt onto glazed or dirty pulleys will cause premature slippage and rapid wear.
