Here at Maxiscoot for an excellent price: Polini 70cc Cast Iron "Corsa" MBK Booster / Stunt (Minarelli vertical).

The kit includes:
- Cast Iron Cylinder "Corsa", d = 47mm, with 5 transfer ports and oval exhaust port
- Two-Ring Piston "Corsa" 10mm pin
- High Compression Cylinder Head, aluminium
- Gasket Set for mounting
- Carbon Fiber Reed Petals, 0.36mm, 2x

Based on the Polini Sport cylinder and redesigned by Polini, this kit is one of the best kits available for MBK Booster / Stunt (Minarelli vertical). The "Corsa" delivers an outstanding performance for a cast iron kit, especially at high rpms, and is very durable on top of that.

A great favourite of even the most demanding pilots, the Polini 70cc Cast Iron "Corsa" MBK Booster / Stunt can reach 10/11hp in combination with the right components (17.5mm carburetor, reinforced crankshaft and racing exhaust).

This cylinder kit (not street-legal!) is one of the most popular kits for everyday use.
