My brother purchased a Yamaha SS 125 cc 5 years ago in 2011.it has traveled around 11000 km and still its condition is very nice. I know that the condition of a good bike depends upon its owners maintenance but trust me he is a college student and its pretty obvious that the bike would be used quite roughly.
But still, its condition is pretty good. the engine is working nicely as well as the other parts. The average is around 45 which is impressive. So I suggest its a good bike to move with.
