The 70cc aluminium mid-race cylinder from the Motoforce Racing series. Great mid-race quality available at the same price that will usually only get you a sport cylinder from well established manufacturers.

Made of aluminium, it has excellent thermal qualities. The nikasil coated cylinder liner is wear resistant, providing long cylinder life. With the right setup, you can expect 12-15 hp.

Equivalent performance to Stage 6 race/ MHR rep but at a budget price. 12-15hp with the right setup up.
Peak power 11,500-12,000rpm so you will need a decent crank and exhaust!
