Hey there, I picked up an 07 650 about 3 months ago as a graduation gift to myself and I have a couple questions about it. I picked it up used with 6400 miles on it and I'm up to 7900 now. I've been looking at tires and was curious if I would be able to fit a larger back tire on the bike without any rubbing etc. If not I'm curious as to what you guys would suggest for mostly street riding "possibly track". Also I wasn't able to find any sports bars for the 07 and was wondering if there were any, or if the sports bars for the 09 / 10 would work on my bike. Thanks for the help in advance.
