The racing version of the Stage6 line, built for us by Athena. This is a high-quality aluminium cylinder with power among the best of the mid-race range.

A very durable nikasil-coated liner together with the excellent heat dissipation properties of aluminium ensures 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 the proper exhaust (e.g. R1200, Yasuni R, ForRace or Carrera 16) this will yield excellent performance.

Depending on the model, it comes with a coated Asso piston, a set of carbon reeds and a variety of base gaskets to adjust port timing and squish clearance.
