I have a 2006 Road King Classic. Right before I come to a complete stop, the bike will pull to the right, even when I have my left leg down. I only use the rear brake. Use the front brake to hold me while stopped. It does this either with the wife on the back or not. So much so that sometimes I have to quickly put my right leg down to catch it.

Any one else have this problem? Any solutions? I know the rear brake is on the right, but I wouldn't think this would cause that much of a problem.

 

Had the front wheel off? Replaced a tire? Is the brake rotor showing any signs of heat? Sounds like you have a caliper hanging up and applying too much brake on the right side. Be sure the spacers are correct. How long has it been doing this?

 

Since you are only using rear brake (not sure why) you may have a warped rotor back there. Does it vibrate while applying the brake?

try using front brake. It is designed to give you about 70% of stopping power.
