Cylinder Kit Doppler Alu 50cc MBK 51, aluminium cylinder ER1 for vintage mopeds. Nikasil-plated aluminium cylinder with 5 transfer ports and an exhaust port with boost ports. The piston comes with 1 ring and a 12mm pin.

The cylinder kit has a lot of torque at mid rpm range and a lot of power at high rpm range and can be categorized as a 50cc sport / mid-race / racing kit. We recommend a 15mm carburetor (at least) and a sports exhaust to unlock its full potential.

The CNC-milled black cylinder head has a bi-hemispherical combustion chamber insert. Without decompressor.
