DetailsOnly one year after having introduced the Evo 3, Polini already presents a new version.
The basic features have been kept: coated aluminium cylinder with T-shaped exhaust port and 6 transfer ports, all in a proven design. The exterior, however, has been completely revamped, with a round shape and side cooling pockets.
The cylinder comes with a one-piece head, which saves cost and is still reliable. Due to the sturdier new flange with three connection points, not all exhaust systems can be used. The bore is still 47.6 mm so the 70cc limit on most racing tracks won’t be exceeded. Depending on the carburettor and the other components used with the cylinder, you can expect performance to be in the region of 20 to 23 hp.
NOTE: This cylinder must be used with a crankshaft with 85mm connecting rod.
NOTE: Requires crankshaft with 85mm conrod and exhaust Polini Evolution 2010!
