Cylinder Stage6 Alu. Racing 70 CC One Ring H2O for Mot. Minarelli 50 LC sp.Ø 10

The racing version of the Stage6 line. Built for us by Athena. Power is among the best of the Mid-Race range, a very durable nikasil plating inside together with the fast heat shifting nature of an aluminum cylinder ensure excellent reliability. 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. Needs either a 17.5mm or even 19mm carb, together with Yasuni R, C16 or ForRace this will yield excellent performance. Comes with a specially coated Asso piston, a set of carbon reeds and a variety of base gaskets to adjust squish clearance.
