Polini drive belt for Yamaha 50cc 4-stroke scooters. Also early short Minarelli/ Malaguti 50cc 2-stroke A/C engines.

Produced for Polini by Gates, a leading manufacturer in power transfer belts. These belts can take very high loads but these are also very flexible, this significantly reduces the effort required to rotate the belt, reducing the loss of power between the engine and the rear wheel, a key feature for drive belts on original and lightly tunes engines without a large amount of power at the crankshaft.
