cylinder kit Airsal T6-Racing 72.5cc 47mm for MBK AV-10, AV-51

72.5cc Aluminium hard coated bore cylinder kit from Airsal. Unlike cast iron cylinders, the aluminium cylinder offers much better heat dissipation making these kits less susceptible to wear or piston failure. The T6 racing cylinder has very good power in excess of the standard sports cylinder and performance improvement is particularly evident in the higher rpm range. Supplied as per image with barrel, piston, ring, pin, clips and required gasket. Original head may be used with this kit.
