Airsal Cylinder Kit "Xtreme" 70cc Yamaha Aerox / MBK Nitro

The Airsal 70cc Cylinder Kit "Xtreme" MBK Nitro / Aerox (Minarelli horizontal LC, 12mm)

The kit includes:
- 70cc Aluminium Cylinder, d=47.6mm, with 7 transfer ports and a bridged exhaust port
- One-Ring Piston, 12mm pin / d=47.6mm
- High-Compression Monobloc Cylinder Head
- Gasket Kit for mounting and for adjusting squish

The 70cc "Xtreme" is a very powerful racing cylinder falling into the lower "Hyper Racing" category. The value for money is pretty amazing, as it is possible, with the right components, to get up to 17/19hp out of it! As it has relatively long port timings, we recommend a large carburetor (24-28mm or more) to unlock its full potential.

Note: you will have to use a 12mm crankshaft with the Airsal 70cc Cylinder Kit "Xtreme" MBK Nitro / Aerox!
