Wave clutch "for race" Vespa Primavera/PK/FL Polini

Polini surprises us with its new Wave clutch, which is fitted with a spring that, thanks to its beehive structure, guarantees excellent flatness of the clutch thrust surfaces and withstands high loads of up to 200 kg.

As standard, the Polini wave spring is set for a load of 80 kg, which can be modified thanks to the adjustment washers available in the kit, which allow the load to be varied up to 200 kg.

The spring is perfectly housed in the clutch hub and the intermediate discs are made of nitrided steel.

The EVOLUTION clutch(230.0503) consists of 4 steel discs coated with high-performance sintered friction material (1.9 mm thick) and three steel discs (1 mm thick) and is recommended for installation on prepared engines over 15 hp. 3 adjusting/preload washers are included.

The FOR RACE clutch(230.0502) consists of 4 steel discs coated with cork friction material (1.9 mm thick) and 3 steel discs (1 mm thick) and is recommended for original or prepared engines up to 15 HP. Includes 2 adjusting/preload washers.
