MOTOFORCE Cylinder Crankshaft Kit Derbi E4

The MOTOFORCE Engine Cylinder Kit is the ideal solution for a complete overhaul of the Derbi Euro 4 engine, compatible with models such as Derbi Senda, GPR 50, Gilera RCR, SMT, and Aprilia RS/RX 50, produced between 2018 and 2020. This complete kit brings together all the essential components for a hassle-free installation, ensuring perfect compatibility and smooth assembly.

The 50cc cylinder, made of gray cast iron, maintains the original technical specifications, including the number of transfers and the shape of the exhaust port. It comes with a two-segment piston equipped with a 12 mm pin and safety rings, ready for direct mounting. The cylinder head, designed to replace the original part, ensures the correct functioning of 50cc motorcycles while maintaining all necessary technical characteristics.

The crankshaft included in the kit faithfully reproduces the specifications of the original component, guaranteeing the same pre-compression and dynamic characteristics. This allows for the replacement of a defective crankshaft without compromising the balance and tolerances typical of Derbi engines.

For a complete and surprise-free installation, the kit comes with all the necessary gaskets, seals, and bearings. Each component has been selected to work in harmony with the others, ensuring optimal performance and long-lasting durability. With this kit, bringing a worn-out engine back to life becomes a simple and cost-effective operation, maintaining the original factory specifications.
