Malossi 50cc Cast iron Cylinder Kit MBK Booster / Stunt (Minarelli vertical, 10mm) - a street-legal kit for everyday road use.

The kit includes:

- 50cc Cast Iron Cylinder "Sport" with 6 transfer ports and oval exhaust port
- Two-Ring Piston, 10mm pin
- High-Compression Cylinder Head, aluminium
- Gasket Set for mounting

Designed for the road, this kit is ideally suited for heavy and/or everyday use. It does not require over-the-top maintenance, and its top quality workmanship ensures durability and reliablity.

You can run it with original carburetor and crankshaft (adjusting of mixture is necessary, though), but you'll get much more power with a 17.5mm carburetor and a street-legal sports exhaust.

Perfect cylinder kit for those of you who are looking for a little more power but don't want to do without maximum reliability.

You can also run this cylinder kit with a 12mm crankshaft, in this case you'll have to order the 12mm piston separately (item no. M348538).
