Cylinder Polini 66cc aluminium Yamaha 50cc 4-stroke LC

If you are looking for more power for your liquid-cooled 4-stroke engine, we have the Polini 66cc Cylinder Kit MBK Booster X 50cc 4-stroke / Ovetto / Neo’s 50cc 4-stroke LC for an excellent price!

The increase of your engine’s displacement – 44mm diameter with 43.5mm stroke – leads to improved performance.More specifically, you’ll notice improved acceleration and take-off and a slightly higher top speed due to increased torque.

The kit does not include a cylinder, it is supposed to be run with the original one.
