Strong Points Stage6 70cc cast iron cylinder
The Streetrace is a lower-priced version the popular Sport Pro aluminium cylinder. Reliable and powerful, this is the perfect cylinder kit for everyday use, with great torque and increased top speed for maximum riding pleasure.
Transfer port layout with 6 ports plus 1 simple exhaust port is basically identical to the more powerful 70cc Sport Pro kit, it was slightly modified to meet the thermal requirements of a cast iron cylinder. The cylinder comes with a high quality 2-ring piston and a HC cylinder head. Maintenance and adjustment are easy, and of course you will find all necessary spare parts in our shop.
Performance characteristics are similar to the Sport Pro – powerful take-offs and acceleration, with an engine speed of approx. 10,000 rpm, with up to 8 – 11 hp, which is 1 – 3 hp more than comparable cylinders. Of course, the cylinder can only unleash its full potential when combined with the matching components, you will find some recommendations below.
The cylinder looks unobtrusive and similar to the stock part. Stage6 has deliberately decided not to display the brand name on the cylinder, instead of a logo they stamped “49ccm” on it.
