Hello, my name is Dan and I am planning on buying a 2003 CBR600RR this weekend. I have one concern over the bike though and I am unsure if it is a normal thing or not. I took the bike out for a test ride and noticed a whine when engine breaking. Now I forgot to check if the whine still existed when I grabbed the clutch because it wasn't really concerning me at the moment. I started thinking about it on the way home. Does anyone else experience any kind of whine when slowing down? I had a GSXR600 last year and that made all kinds of noises, but all of them were normal and I just cant put my finger on what this could have been. Maybe just a normal thing and I'm over thinking? Also, I looked at the radiator and noticed that is was bent up pretty bad (Pic Below) It doesn't leak and it still cools good but its kinda sketchy on how that happened, I cant even think on how that could happen. Anyone? Problem in the future?
Some info that might be useful: Bike has been down at parking lot speed, seems like it has been messed with but everything is in good shape and good working order.
