Polini 80cc Cast Iron Cylinder Kit Sport MBK Booster / Stunt (Minarelli vertical) - an excellent everyday use cylinder for an excellent price, here at Maxiscoot.

The kit includes:
- Cast Iron Cylinder, d = 47mm, with 5 transfer ports and oval exhaust port
- Two-Ring Piston, 10mm pin
- High Compression Cylinder Head, aluminium
- Gasket Set for mounting
- Carbon Fiber Reed Petals, 0.35mm, 2x

Since it is made of cast iron and has a two-ring piston, it is ideally suited for intense everyday use, and is also known for its robustness and power, especially at mid to high rpm range. It can reach appr. 7hp when combined with the right set-up (17.5mm carburetor and sports exhaust).

70cc displacement, meaning it is not street-legal and is reserved for the race track (or closed-off roads).
