I do not know who made it. It was on my sons bike when I bought it. It has done us fine, I am goin with a longer one for next year. I have never had it adjustaed to any other lenth. I am including the swingarm, stock stlye carrier, and will include the chain, it is a vitos gold chain about two months old. It is not a high tensile strenth chain.. I dont want you to think you are getting a 200.00 chain. It put my son in the 4.20's with no issues, but.. There are no issues with the swingarm or carrier, it is straight, bearings are good, however it could use repainting. It does have wheelie bar mounts, but bar is not included unless local pickup and extra cost for bar can be talked about.
235.00 shipped
