These bare steel fat bob fenders have a chain relief on the left side and can be run on any left side drive motorcycle like Triumphs, Yamaha XS650, Harley Davidsons, etc. These are really sturdy, heavy duty fenders. Run the whole thing or modify it, section and narrow it, use only the end 'flip' for that bratty look or whatever you want to do. 7" wide, 28" measured straight across end to end and 38" measured along the curve of the fender. These are a proper radius for an 18" rear rim, or a 16" rear with a high sidewall vintage style tire.
