Cylinder kit Airsal sport 163.4cc 60mm

Airsal high-performance cylinder kit 165cc capacity, with gasket set, piston, rings etc. Hard chromed liner. 165cc gives engines notably better torque in the lower rev range. Before ordering, please ensure that the cylinder base opening is suitable and there is sufficient space on the crankcases. Opening must be worked where the clearance is tight. Outer diameter of the cylinder liner/sleeve (that protrudes into the crankcase) is 62mm.

Please note: If purchasing this kit for the Sym 125cc scooters, please ensure your engine is the GY6 version (cylinder head stud holes have a distance of 63mm hole to hole, outside to outside measurement).
