Athena 125cc cylinder kit for Yamaha 125cc LC 2-stroke engines. The cylinder kit consists of an aluminium cylinder, a matching head and gaskets. For the exhaust control a suitable rotating cylinder is included. The cylinder is perfectly suited as a 125cc replacement cylinder with moderate performance optimization when replacement is unavoidable due to piston seizure or wear. According to Athena, the power increase turns around about 2 HP. A control of the carburetor tuning is an absolute must even with such a small performance increase!
