Doppler 50cc Aluminium Cylinder Kit "ER1" MBK 51 AC; Nikasil-plated aluminium cylinder with 5 transfer ports and an exhaust port with boost ports. It comes with a single-ring piston.

The kit has considerable torque at mid rpm range and a lot of power at high rpm range and can be categorized as a 50cc racing kit.

We recommend running it with a 15mm carburetor (minimum) and a high-rpm sports exhaust (such as Doppler or Bidalot). Even though it is possible to use your original cylinder head, we recommend replacing it with a high-compression cylinder head to improve performance.
