Airsal 48.8cc (38mm) cylinder kit for new generation Puch Maxi scooters incl. all necessary parts: gaskets, piston, rings etc. Cylinder head not included. Aluminium design for improved heat dissipation over cast iron cylinders. T6-Racing is up there with 70cc cylinders and goes well with racing exhaust systems such as: Tecnigas TREK, Next R, Tecno Evolution or Stage6 Pro Replica and Pro. Not a high end cylinder, but great value for money for those who do not want to install a 70cc cylinder.
