Cylinder Kit MotoForce Racing 70cc cast iron Minarelli vertical AC

The Perfect 70 cc Cast Iron Cylinder for Everyday Use

MotoForce Racing cylinder kit 70 cast iron for 50cc models with Minarelli vertical AC engine (Yamaha BWs, MBK Booster etc.)

Perfect choice if you want to replace the original cylinder with a more powerful but equally reliable model.

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 power, the MotoForce Racing cylinder makes about 2 to 3 horsepower more than the stock cylinder and is very torquey. Due to 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 off-the-line acceleration, let's go!

To ensure performance and reliability, we recommend combining the cylinder with a carburetor with at least 17.5 mm diameter, a tuning CVT and a tuning exhaust like the perfectly matching Stage6 Pro Replica.

All in all - great 70 cc cylinder for everyday use that offers great value for money.
