Cylinder head air DOPPLER RADIAL CNC machined mass high compression without decompressor 50cc Ø39mm on MBK 51 / motobecane av10

Ideal for the 50cc kit DOPPLER ER1 or other brand or even on an original high engine, here is the DOPPLER RADIAL CNC high compression cylinder head. This model is much improved in relation to an original cylinder head and even in relation to the DOPPLER ER1 cylinder head. On the one hand it is made of the best aluminum, machined mass, anodized, then it has a well-worked high compression combustion chamber with a tapered shape with a polished finish. It offers a marked improvement in cooling compared to a standard cylinder head! Calorie transmission is improved by its design and the quality of its alloy!

The cylinder head gasket is fitted with a Viton O-ring. You can of course if desired use a standard aluminum joint (check your squish carefully).
