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

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