Metrakit Pro Race 4 80cc Cylinder Kit 50mm Derbi EBE050 up to 2006

The Metrakit Pro Race 4 cylinder kit is a high-end racing cylinder designed for Derbi old type engines up to 2006 (EBE050). Known for its excellent finishing and high-quality materials, this cylinder delivers outstanding performance.

With a 50 mm bore, the cylinder produces approximately 78cc displacement. The advanced aluminium construction allows the engine to achieve very high performance levels.

The cylinder features a dual cylinder head system (inner and outer head) for improved cooling and combustion efficiency. Installation can be done without modifying the engine crankcase.

For optimal performance it is recommended to install a reinforced crankshaft, a larger carburetor (for example Polini CP) and a big bore exhaust system. The engine should also be properly tuned after installation.
