I think I don't have a TT500 1 It does not have the two speed transmisson on it .it has the variable speed set up with the fan belt .2 the rear break looks to be a drum break not a disk . The front is a disk . There are alot of tt500 parts on this bike and alot of something else . Please tell me what I have . I think it might be a parts bike made to look like a TT500 .I think I got f***ed :shrug:
