Polini Evolution 3 cylinder for Minarelli LC

The Evo 3 tuning cylinder offers some subtle changes compared to the previous version. The healthy concept of the Evo 2 has been retained here and only minimally changed. The exhaust has been massively revised. Polini has abandoned the concept of the main outlet with two secondary outlets. Instead, the Evolution Three has a split T-port. This offers sufficient time cross-section to top the Evo 2 in terms of performance. The completely redesigned Evo 3 scratches the 25 hp mark.

With such orgies of power, it goes without saying that the engine should be built without compromise. The crankshaft in particular whines for mercy faster than you would like. A tip here are our BGM Evolution shafts.
