Here is a 50cc kit from TOP PERFORMANCES , in cast iron with its reinforced piston and its bi segment it is really very solid but also powerful by its well-defined diagrams, its diameter of 40mm and its admission.
It comes with piston, seal pack, segments, its blue cylinder head is with high compression chamber....
We recommend it to those who want to ride every day and have a lot of torque and peak. This type of cylinder can do a good 25,000 km by changing the piston at 10,000 km. It also has the reinforced O-ring cylinder head gasket which is not negligible on this type of engine.
As an option we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement of the piston and the lower skirts is also included in this modification. Count a little extra time for this preparation!
