Classic Vespa Polini Performance Parts - Clutch Kit Polini Race for Piaggio Ape, Vespa Primavera PK 50, 125 Smallframe
Clutch kit "Race" with reinforced 4-disc clutch and shaft spring from Polini suitable for Vespa with central spring like Vespa Primavera PK 50, 125 and small frame models. Suitable for engines in original condition as well as tuned engines up to 15PS.
The innovative wave spring has been designed with high precision. It achieves an even distribution of pressure on the friction surfaces through its honeycomb structure. It can thereby build up a pressure of up to 200kg. To do this, the contact point of the spring must be adjusted using the adjustment washers included in the kit. The standard setting is 80kg. The clutch hub has a special centering seat to ensure that the wave spring is optimally seated. The clutch hub and the separating discs are made of nitrite steel (increased coefficient of friction).
Tip: Polini recommends soaking the cork discs in oil overnight before installation.
The Polini 4-disc clutch is alternatively also available in the "Evolution" version with pads made of sintered metal for tuning over 15hp (230.0503).
