To name a few "maybe not so bad" things:
- difficulty clearing the rear brake and shock
- could rub the inside of the swingarm tube
- change in steering geometry...maybe only a racer will notice the increased effort to turn the wheel due to the change in profile
- bike sits lower, so the centerstand and sidestand don't function normally
GREAT points - especially the steering geometry change. One wouldn't think there would be that much difference, but my /7 rolled and steered (much better) after changing back to correct size/profile tires.
