I am stationed at Ft. Hood and i have to take a refresher course and the advanced sport bike course when i get back from this deployment in december and I stretched my bike about 7 inches when i went on leave. i was wondering if anyone has done a course similar to this on a stretched bike and how it is? i have stock rear tire and it turns well but i dont know what goes on in the class. i could take it off for the class but i could probably learn something there with having it on as well, any suggestions?? its not that i cant ride, never had a long bike before open to all opinions thanks.
