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 minimal changes have been made. Massive is the reworking of the exhaust. Polini has abandoned the concept of the main diffuser with the two secondary diffusers. Instead the Evolution Three features a split T-port. This offers enough time cross section to beat the Evo 2 in terms of performance. So the completely made Evo 3 scratches at the 25 hp mark.

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