Stage6 improved their R/T long-stroke crankshafts and redesigned the crank webs. The 16mm crankpin was replaced by a 18mm one for improved durability. The webs are reinforced, the thrust washers are silver-plated, the 90mm connecting rod is forged.
Originally developed for use with Stage6 R/T 95cc cylinders, but it can also be used with other large displacement cylinders.
