This is the entrance to the world of racing crankshafts. The crank is based on an Italian GP crank. The crank webs are pretty good and so is the con rod. These are a superb basis to convert to a tidy crank.They are equipped with high quality big end bearings by European origin. Equipped in this way the crank is trouble free and even the power of a TS1 kit isn t a big issue in most cases.
