Here is the ATHENA RACING 50cc kit for derbi euro 3 and 4. This high performance kit has large diagrams, a high compression ratio, a single-segment piston, a cylinder head, several gaskets. base to make the squish ... We are on very serious equipment! The materials are of good quality and the machining, castings of good quality, nothing to do with the low-end cylinders. We are however on a very affordable rate. A psoer with a pot, reinforced clutch, 19 to 24mm carburetor, well released ignition.
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 to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
