Perfect crank for Sport and Racing cylinders. The crankshaft is of high quality as you know it from Stage6 and is balanced to 16,000 RPM as well as durable thanks to its robust metal construction, even when subjected to high revs.
The crank is suitable for 50cc Sport cylinders and up to 90cc Racing cylinders, this makes the HPC crank an extremely versatile choice, pretty much regardless of the setup you ride with.
