The Stage6 Sport Pro 70ccm MkII cylinder kit has been upgraded in several points and the high quality is of course preserved. The performance has got a notch up, so it now provides up to 2hp more, which i.a. due to improved design of flushing channels and exhaust port. Stage6 is aware of many ports their cylinders and improved heat dissipation therefore has a lot to say. Precisely for this reason, the top piece has also been upgraded with cooling fins on the top and bottom. The piston is a Stage6 R / T Replica with a curved top and the same type of piston ring of 0.8 mm as i.a. also used on the Stage6 R / T stamp. For this cylinder kit a spark plug with a long thread must be used and it is delivered complete incl. cylinder head, gaskets, piston ring and accessories therefor.
