MALOSSI gear set Z 55/40/37/36 for Vespa Cosa 125

The MALOSSI gear set is intended for the Vespa Cosa 125 from the 1988-1997 model year range. With the tooth numbers Z 55, Z 40, Z 37 and Z 36, the set enables a gear ratio that differs from the original. This allows the coordination of the four gears to be adjusted according to the respective needs.

Version for resilient gear work

The gears are made of specially hardened steel. They are manufactured on CNC hobbing machines; The contact surfaces are then ground. Small depressions in the contact surfaces between the gears support the transport of oil. This improves lubrication on the surfaces where the gears slide against each other.
