This is the type of info to research when doing a serious dragster restoration or period correct drag bike build. The AMA did not want anything to do with Motorcycle Drag Racing in the 50's & 60's so rules varied from strip to strip around the country. This AHRA booklet is a neat little peice of the puzzle and probably close to what most strips were doing. I do not know if the NHRA had any Motorcycle Drag Racing Rules at this time or not. The AMDRA (American Motorcycle Drag Racing Association) was the first serious motorcycle drag racing sanctioning body and was founded in 1969 or '70. If anyone has any old literature on motorcycle drag racing rules please email: email@example.com
And the AHRA was keeping track of it's records as well. This clip pulled from a 1966 motorcycle magazine.
