Clutch Springs POLINI Sport

for Speed Clutch 2G, for
PIAGGIO Leader/Quasar 125
-300cc 4-stroke, AC/LC
4 pcs, for P249041/P249042

When enough rpm‘s are reached, centrifugal force moves clutch plates apart to mesh with the clutch basket which in turn transfers power to the gear box. Now that you see how the clutch works, it‘s easy to understand how important spring preload is for clutch springs and their infl uence on the clutch.

Harder springs delay the reaction of the linings towards centrifugal power, delaying contact with the bell until higher rpm‘s - getting you aggressive acceleration.


Small, but very important tuning part. Torn clutch springs can offer some hefty surprises. Ask Moritz about his unintentional rodeo ride into an intersection after a a spring blew. Lucky for him no one was in his way at the time.


Time can run out on even the sturdiest clutch spring. High time for clutch replacement parts from POLINI & MALOSSI:


TECHNICAL TIP! Friction is controlled by the clutch spring strength (thickness of spring wire). Hard springs give you a real advantage by letting loose first when your motor is revved up, getting your motor more power right from the start.


SIP TIP! New clutch nuts, positioning tools.
