Polini Cylinder Kit \

A great favourite on the race tracks for years: Polini 50cc Aluminium Cylinder Kit "Evolution" MBK Ovetto \/ Neo’s, 10mm (Minarelli horizontal AC, 10mm pin).The kit includes:

Aluminium Cylinder, d = 40.2mm, with 5 transfer ports and bridged exhaust portSingle-Ring Piston, 10mm pinHigh-Compression Aluminium Cylinder HeadCarbon Fiber Reed Petals (2x), 0.35mmGasket Kit for mountingThis street-legal cylinder kit is definitely one of the most powerful 50cc kits on the market. Originally developed for the race track, it can just as well be used on the road.

We recommend combining it with a 17.5mm carburetor (minimum), a reinforced crankshaft and a sports or racing exhaust; moreover, regular maintenance is essential if you want to use it as an everyday cylinder (regular replacement of piston ring\/piston).
