I have a 1975 Yamaha mx 400. The handlebars that were on it when i bought it are from a much smaller bike. Im trying to find out the width and rise of the factory bars. There is a motorcycle salvage yard nearby with unmarked vintage bars. I'm trying to find the right bars or something very close to factory size. There is some nice bars from a 78 Yamaha dt 175 that are in good condition but im not sure if they are close in size. Help me guys
