DetailsThe Perfect 70cc Cast Iron Cylinder for Everyday UseThe MotoForce Racing 70 cast iron cylinder kit is the perfect choice if you want to replace the original cylinder with a more powerful but equally reliable model. This kit is compatible with 50cc models with vertical AC Minarelli engines (for YAMAHA BWs, MBK Booster, etc.).The MotoForce Racing 70cc cast iron cylinder has 5 transfer ports, a single oval exhaust port, a 2-ring piston (47mm diameter) and a high compression cylinder head. In terms of horsepower, the MotoForce Racing cylinder produces approximately 2-3 more horsepower than the stock cylinder and is very torquey. Thanks to the better torque, there is less need to use the high rpm range, which is easier on the engine and maintains engine reliability. And of course, your starts will be much better – direct throttle response, great acceleration from the start, go!To ensure performance and reliability, we recommend combining the cylinder with a carburettor with a diameter of at least 17.5 mm, a tuning CVT and a perfectly matched tuning outlet such as the Stage6 Pro Replica. Ultimately, a great 70cc cylinder for everyday use that offers great value for money.
