With the 70cc Streetrace grey cast iron cylinder series, Stage6 offer a bargain version of the popular SportPro Aluminium cylinder. The transfer port layout has been adopted from the high-performing 70cc SportPro and slightly modified in order to fulfil the thermal demands of the cast iron cylinder. Stage6 have gone for a piston manufactured by the renowned Italian company Vertex Pistons. The performance characteristics mainly correspond to those of the SportPro; a bit more power when accelerating coupled with 0.5 hp less peak power. The ideal rpm range is around 10,000 rpm. It is recommendable to use a 70cc sport exhaust system. When it comes to looks, the cylinder is unobtrusive and similar to the stock part. Stage6 have deliberately decided not to display the brand name on the cylinder and have gone for the writing "49ccm" instead.
