I pulled the rear tire and rim off the CB750, getting ready to swap a Dunlop TrailMax 130/80-17 onto the Comstar rim. I think I will take my own advice, and replace the brake shoes while I am at it, they are OEM Honda shoes, so they could be originals. The TraiMax looks like a nice grippy tire, they have good reviews, and it cost me $20 at my buddies cycle salvage, was on a BMW GS adventure bike. The drum looks like new, which is a nice surprise! Will get to lube up everything, and check the chain lube, brake cam, etc while everything is apart.
