Big bore ceramic cylinder kit for 250cc Kymco and identical PGO engines.
With the Naraku cylinder kit we offer for the first time on the German market an affordable big bore upgrade kit for 250 quads and scooters. The cylinder is a high quality aluminum cylinder with hard chrome plated cylinder bore. Qualitatively, the kit is equal to the original cylinder and the Athena replica, but we can offer this cylinder at a much lower price. All necessary gaskets etc. are included. Furthermore, this kit does not require any milling work on the engine housing. Externally, the cylinder is not recognizable as a 300cc cylinder.

The kit comes complete with all necessary parts and gaskets. Nothing has to be ordered additionally.

Please select spare parts for this kit from the list below.
