Cylinder kit from the Spanish manufacturer Airsal. All necessary parts for assembly are provided eg gaskets, piston, piston rings and so on. The Spanish brand supplies aluminium constructed cylinders with hard chrome plated cylinder linings, which in comparison with cast iron offer considerably better heat dissipation. This makes the cylinder less prone to wear and piston jamming as a result of temperature problems. Cylinder kit exclusively for air cooled 125cc 4-stroke engines from SYM Symphony as well as Peugeot Tweed Maxi-scooter.
