Airsal 50cc racing cylinder kit, complete with gasket set, piston, piston rings etc. (cylinder head not included) The T6 Tech-Piston matches the T6-Racing exactly and also features a 3-piece outlet, but the difference lies in the single piston ring. Aluminium construction with hard chrome lining. The "50" T6 Tech-Piston is up there with 70cc sports cylinders, revs higher and can be tuned for around 8bhp. Good exhaust systems for the cylinder include: Tecnigas TREK, Next R, Tecno Evolution or Stage6 Pro Replica and Pro. Not a high end racing cylinder, but good value for money if you don’t fancy a 70cc conversion. Designed for a standard crank with 10mm gudgeon pins.
