Stage6 scores again! Here's the successor of the already very powerful 70cc racing kit: Stage6 70cc Racing Cylinder Kit MKII, 12mm piston pin, MInarelli horizontal LC (Yamaha Aerox / Jog / MBK Nitro / China-based hybrid Minarelli 2-stroke and many other vehicle models).
Stage6 engineers completely revised the design of the Stage6 70cc Racing cylinder and managed to get impressive performance out of this 70cc racing kit. Out of the box, it yields 1hp more than its predecessor. This means that the MKII racing cylinders will now reach a whopping 17 to 19hp; this is, of course, in combination with the appropriate components (internal rotor ignition, bigger carburetor, oversize variator, racing exhaust etc.). And if you're really into engine tuning, you can squeeze even more out of this outstanding cylinder, up to 20hp is a realistic estimate. The output of this 70cc cylinder definitely positions it among the top racing cylinders on the market.
On a technical level, the MKII is an aluminium cylinder with extremely resistent hard-chrome coated bore. Stage6 replaced the former flathead piston with a dome piston with 0.8mm ring, basically a replica of the high-end Stage6 R/T piston. Dome pistons increase compression ration and consequently performance. Thermal characteristics are excellent, with a well-cooled divided, bridged exhaust port and a one-piece cylinder head with large cooling ducts. The cylinder has 6 transfer ports, port timings were raised to 190°-130°.
The kit includes cylinder, cylinder head, 12mm piston with ring and pin and all the gaskets needed for mounting.

This 70cc racing cylinder is NOT street-legal for some countries.
Note: the temperature sensor must not be longer than 18mm, otherwise it will touch the cylinder head wall.
