I never take mine off but maybe it fits alittle different than yours. I don't want to keep taking the bolts in and out of the brakes.
EDIT: Well, I just went out and looked at mine. It does not hit the rad with the bars straight like you would ride but if you go full lock (like locking the forks) it does hit. Yea, my rad is banged in some. Thanks for the heads up North. It has been on for two or three years.
