We offer the Top Performances Cast Iron 70cc 'Racing' Cylinder Kit MBK Booster / Stunt (Minarelli vertical) : definitely, alongside the 'Corsa', the most powerful cast iron 70cc cylinder kit on the market!

The kit includes:
- Cast Iron Racing Cylinder, 47mm diameter, with 7 transfer ports and oval exhaust port
- One Ring Piston, 10mm pin
- High Compression Cylinder Head, aluminium
- Gasket Set for mounting

Even though made of cast iron, the Top Performances 70cc Cast Iron 'Racing' MBK Booster / Stunt is a racing cylinder with excellent performance regarding acceleration as well as top speed. With 7 transfer ports and longer port timings, this cylinder kit is definitely an original design by Top Performances and not just a 'remodeled' Sport cylinder. It comes with a one-ring piston (10mm pin) for powerful performance!
