(10mm Gudgeon pin) The Corsa is a Polini Powerfull Mid-Race 70cc cylinder improved from the Polini Sport 70cc cylinder. Extreme port timing, polished exhaust port and increased primary compression result signifiant power increase compared to standard 70cc cylinders with very good reliability. The piston is equipped with a chrome and a grey cast iron piston ring. To reach maximum power, the cylinder should be used in conjunction with a racing exhaust and bigger carburetor (21mm). We also suggest to use renforced crankshaft. Note: you can only use long reach spark plugs with this model (such as BR9ES or BR9EIX).
