I have a Sportster iron head rear hub and I am wanting a smaller drum and and less teeth on the rear sprocket.
I think I heard once that a Triumph pre unit drum will bolt up to a Sportster hub. Apparently these are a 7 inch drum and the sprocket will bolt on.
Has anyone done this?
If not does anyone have a Triumph 7 inch drum witha bolt on sprocket sitting around that you can take some measurements from.
I need the center hole size and the PCD of the eight mounting holes.
Any other suggestions for a smaller drum on a Sportster hub would be appreciated.
