PERFORMANCE FIXED PULLEY HALF MALOSSI VESPA PRIMAVERA SPRINT 3V 150

PERFORMANCE FIXED PULLEY HALF MALOSSI PRIMAVERA SPRINT 3V 150 61-18066B

The Malossi 3 valve pulley half has larger cooling fins for improved belt cooling in the transmission.

The pulley fan half of the transmission are replacement parts, similar to roller weights or drive belts.

Often the drive belt can cause grooves to be worn into the inner flanks of the original pulley half, resulting mainly from stop and go riding in urban conditions. These grooves can be compared to ruts on the street, with the drive belt hanging their instead of gliding smoothly further, resulting in a noticeable power-dip while accelerating.

This makes it essential to check these surfaces for wear during every service and prior to tuning upgrades to a sport-orientated pulley half.
