oh the benly? i would think so, it is a smaller bike. There are two factors. is the rear fender the same width as the 305 dream. if so, it would fit fine. and are the shock bolts in about the same place. we can measure that out if you want. I have these listed on the honda305 forum right now. Worst case is just have a couple pieces made for the bracket to make the adjustments.
pics of the bracket, hope this helps, FYI the bracket is now powdercoated black.
