There are two variations of Stage6 cylinder kits; one is made from cast iron, the other from aluminium. The cast iron line is for the budget-minded entering into the world of tuning, with its slightly lower specific power output there are no problems with overheating. The aluminium line features three versions of Stage6 cylinder kits; the Stage6 50cc Aluminium-Line, the 70cc Sport PRO and the 70cc Racing Version. All three versions are made from aluminium with an extremely durable and hard-wearing plating. This combination makes for highly efficient and reliable cylinders made to the tightest tolerances possible.
