70cc cylinder kit for Derbi Euro 3-4, crankshaft, bearings with seals, and Allpro engine gaskets

AllPro kit consisting of a 70cc Iron Cylinder, reinforced Performance crankshaft, bearings with crankshaft seals, and a complete engine gasket set, designed for Derbi Euro 3 D50B0 engines. This assembly offers a balanced setup to increase engine performance while maintaining good reliability in 70cc sport builds.

The AllPro Iron 70cc Cylinder Derbi Euro 3 D50B0 is made of cast iron, a material recognized for its wear resistance and ease of maintenance. Its larger displacement configuration increases torque and improves response compared to the original 50cc cylinder, making it an ideal option for users seeking a performance upgrade without reaching an extreme racing setup.

The cylinder design is optimized to offer a good balance between performance, durability, and ease of tuning. Its iron construction allows reboring in the event of wear, extending the service life of the assembly and making engine maintenance easier.

To withstand the greater loads generated by the 70cc cylinder, the kit includes the AllPro Performance reinforced Crankshaft Derbi Euro 3 D50B0. This crankshaft is designed with reinforced materials and treatments to withstand greater stresses than the original component, making it an essential part in builds where improved engine reliability is desired.

The assembly is completed with the AllPro crankshaft bearing and seal kit and the complete engine gasket set, necessary components for correct installation, ensuring engine block sealing and guaranteeing proper internal lubrication.
