The most racing kit cast of the Italian company PARMAKIT the RACING is a very powerful model so Ø47mm 70cc cast. PARMAKIT equipped this kit with a piston has high silicon content with work on the skirt to improve the scanning and two heavy-duty segments for maximum torque. The cylinder is a very good cast iron cylinder, the workmanship is good, the escape door oval, admission is revisited and charts are quite high. The cylinder head is a high-compression model journal for better cooling, the combustion chamber is high compression, truncated and polished.
