The power of the Stage6 *RACING 70cc* cylinders is among the best of the Mid-Race range.

Aluminium cylinder with very durable nikasil plating. The main differences to the Sport Pro are longer port durations, a bridged exhaust port which makes for huge port time area and a higher compression ratio.

Excellent performance with either a 17.5mm or 19mm carb together with something like Yasuni R, C16 exhaust. Comes with a specially coated piston, a set of carbon reeds and a variety of base gaskets to adjust squish clearance.
