The Casa Performance PowerMaster STD is the new cassette clutch for classic Lambretta S1+S2+S3+DL+Serveta engines. This range of clutch is successful used as standard in all the Casa Performance SSR & SST engines, with NO issues with +50BHP.

The Casa Performance PowerMaster STD can be used with both standard or tuned machines. The kit has 7 plates and 10 springs. It comes with its holding tool, clutch nut and washer and SX and GP nipples. No sidecasing spacers or other type of machining required. Simply Plug'n'Play with both original sidecasing or our CasaCover.

Crownwheel, spider and upper plate are stainless made, CNC machined. This type of machining leaves the clutch very light, only 1800gr and superstrong. After a special heat treatment, both crownwheel and spider were ground to provide the best chain alignment and no power consumption. The clutch has a real "Thrust bearing system" who helps and keeps the clutch action featherweight!

The Casa Performance PowerMaster STD is a "Cassette Clutch", so it can be dismantle in one piece! This can helps maintenance operations or other parts removal. No more time wasting! Simply fit and forget!
