This is the Cosa clutch, a very much improved version of the standard P range clutch. Centrally located are eight springs. This makes the operation of the clutch very smooth. The surface of the clutch plates is slightly larger.
This set up is eesily capable of sustaining power figures of 17 hp. If your engine is even more powerful you have to fit reinforced springs. This setup sustains the power of engines with more than 30 hp.
Also have a look at the reinforced version. We recommend the BGM Pro Street gear oil (BGM 2025, corresponds to specification API GL-3).
