The Stage6 Streetrace 70cc cylinder kit is made of cast iron and the design of the flushing channels and exhaust port is very similar to the Stage6 Sport Pro. However, the performance is lowered a little compared to the Stage6 Sport Pro, so that there are no problems with the heat and at the same time the durability is absolutely top notch. Stage6 has deliberately not written its name on the cylinder, but instead simply written "49ccm" so that it can be confused with the original cylinder. As mentioned, the cylinder is made of cast iron and we therefore recommend a drive of around 200km. For this cylinder, a spark plug with a short thread must be used, we recommend an NGK BR8HS .. The kit is delivered complete incl. gaskets, piston rings, etc.
Note: This cylinder kit is with a ø10mm cross pin.
Note: The cylinder cannot be fitted to models from 2003->, unless the restriction in the engine block is removed. If the cylinder is fitted, it is no longer possible to use the original or other Euro2 exhausts. Both parts apply to models from 2003->. This does NOT apply to PGO engines.
