hellow everyone, i simply wanted to know if anyone knows if there are any comoon problems to these bikes?

is there anything i should look for on these bikes?

i ve seen GG from 2007 and newer with broken swing arms,

Not seen Broken Swing arms except on the Mag Alloy Raga's which they stopped in 2007. Generally the mounts on the exhaust do break on the "old" frame but I would have thought they would have been re-welded by now. The Bolts holding the airbox on at its front end can put a hole in the tank but again mostly these were replaced by shorter ones that didn't touch the tank. That's about it really.
