The 70cc cast iron cylinder from the Streetrace series by Stage6 is a low-cost and high-performance variant to the standard 70cc cast iron cylinders by Malossi or Polini. The overflow layout was taken over from the powerful 70cc Stage6 SportPro and minimally modified to meet the thermal requirements of the cast iron cylinder.
For the choice of the piston, Stage6 relies on the renowned Italian manufacturer Vertex Pistons. The performance characteristics largely correspond to the SportPro: slightly more power in the suit, 0.5 hp less peak power. With an appropriately supporting exhaust (e.g. Yasuni R, Stage6 Pro), the power revs are around 10,000 rpm. Visually, the cylinder was designed inconspicuously and close to series production.
Stage6 deliberately refrains from casting the brand name and prefers to show the inscription 49ccm at this point.
