You're looking for ultimate power for your 70cc engine? Maxiscoot has it - Polini 70cc Cast Iron Cylinder Kit "Corsa" MBK Ovetto / Neo's (Minarelli horizontal AC, 10mm).

The kit includes:

  • 70cc Cast Iron Cylinder, with 5 transfer ports and simple oval exhaust port
  • Two-Ring Piston, 10mm pin
  • High-Compression Cylinder Head (long reach spark plug)
  • Gasket Kit for mounting

Based on the 70cc Cast Iron Sport cylinder by the same company, this cylinder kit is designed for even more power. Polini redesigned the cylinder resulting in longer port timings and in a differently shaped exhaust duct. These modifications lead to an increase in power - it can reach appr. 10/13hp, in combination with a 17.5mm carburetor (at least) and a sports exhaust. The piston included in the Corsa kit is also special, even though it remains a two-ring piston with a 10mm pin.

The cylinder kit is NOT street-legal!

Note: you can only use long reach spark plugs with this model (such as B9ES or BR9ES).
