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.
Included in delivery:
- cast iron cylinder 47mm bore
- 2-ring piston, 12mm pin
- aluminium cylinder head
- gasket set
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.
