The successor of the popular Stage6 70cc Racing cylinder is the Stage6 Racing MKII 70cc.
It has been completely revised and has 1hp more out of the box.

This is a completely re-designed aluminium cylinder with high-strength Mahle/Nicasil coating. The former flat piston has been abandoned in favour of an R/T replica with 0.8mm ring and domed crown and the thermal stability has been improved in all areas.

Features: generous flushing of the bridged exhaust port, pentagonal design and inner cooling fins, one-piece head with scavenging passages - to name but a few of the improvements.
With the right components, this cylinder yields 17-19 hp right out of the box and there is still enough material left for everyone to do some own work and get more than 20hp out of this cylinder !

Use short reach B9HS or BR9HS plug with this kit.

*Choose between 10mm (standard) or 12mm (oversize) gudgeon pin.
