The Stage 6 Racing MKII  is the successor to the very successful Stage6 70cc Racing cylinder and is a completely revised version with even more power straight out the box.
A complete revision of the aluminium cylinder with high strength metal nicasil coating.  Improvements include complete thermal optimisation (new internal cooling channels and fins). Instead of a flat piston it now includes a Replica of the R/T piston with a 0.8mm Ring and curved piston head.

With the correct exhaust/ components and setup up this is capable of 17-19 HP out the box. Designed with tuners in mind this kit is capable of over 20HP with porting work. 

NOTE: The temperature sensor (incl. thread) must not be longer than 18mm, because otherwise it could knock against the cylinder head. Please check dimensions before mounting!

Choice of 10mm or 12mm gudgeon pin- use BR9ES or B9ES spark plug.Stage6 Part No. S6-7416606, S6-7416608
