Title: Aftermarket Frames For 1975 Yamahas
Post by: Tahitian_Red on July 17, 2012, 05:10:01 am

Did Red Line or Pro-Fab make an aftermarket frame for the early mono-shockers?

I think pro-fab did.....but for the works "OW's" only....I think theres a blurb on Terry Goods site "MXworksbikes".... look up OW13....basically the std frames where breaking at the headstock. A guy in NZ that I know raced  YZ250/360B's for Tim Gibbes said even the production ones broke as the tracks got rougher....he said we always had a welder at the track to repair the frames.

I guess my Trackmaster motocross frame to suit the Yamaha YZ125 X/C might fit the bill. It takes the dodgy period monoshock out of the equation, replacing it with a good honest twin shock set up. ;D If anyone did make an aftermarket frame for the mid seventies YZ's it'll be sure to be an American, I vaguely recall  seeing a Pro-Fab or C&J (or perhaps both) monoshock frame.

Nice!
But they dont list it in any of their catalogs, so i recken it might have been a sponsored rider only thing
