I am considering going to a 21" front rim and tire on my RK custom. I would also like to change my front brakes from dual to single. My question is how much will it affect the stopping power (if any). If anyone has done this all comments would be welcomed.
I did the same thing on my 05 EG with a 6 piston pm caliper and 9/16 mastercylinder, it works great, just as well as the stock set up. I was concerned to that there might not be enough break with one caliper on a heavy bike but no problem at all. Good luck.
