I don't know for a fact that there is....but I bet there is.
The CB200 used a mechanical disk that was the same as the early MT125R race bike ( Evil?), the later model MT125R went to hydraulic...and I bet it still fit the same forks. And I think the CB125 used the same mechanical disk as the CB200....if you see what I'm getting at....there was a transition period from mechanical to hydraulic...probably using the same components except the caliper.
(forget finding the MT125R parts...that's not going to happen)
ok i get what your saying. I hope to get this 74 cb125 and build something out of it. I found that powroll makes race piston kits for the old 125. 145cc and a 175cc bigbore stroker kit.
i might go with the 145cc 9.5:1 piston kit and try to upgrade the frnt brakes. but im having a hard time trying to find a vintage type race cam for the cb125. i want to look into see if some later type honda cams would fit. i just want to built this cafe racer as close as to the real thing that they used back in the day. if i could get some old cam specs I/ll just get the cam welded up and regrind into a more race profile.
motorcycle nut. anything that i can take and make it go fast.
