It seems that RWB had a 150 speed limit, most in the class ride in, it is the chance for anyone with a MC license to race on the Bonneville Salt Flats and get a time slip for their bike in a timed mile. It is cheap, entry level like the 130 club in the USFRA. Many RWB competitors return to run for AMA records.
Everyone remember, the rules are the minimum requirement, and it is your butt.
