I have recently purchased a 2012 CBR250r. The bike had a 6 inch stretch on it when i purchased it. I'm assuming from the look on the back tire when i got it, it was more than likely raced. What are y'all opinions (Pros/Cons) on the bike having that small stretch on it? It runs great, it needed a little cosmetic work because the last owner really didn't clean it up much.
