In Europe or the US the seller would never be able to get rid of that bike for that price considering age and mileage. However we have a very different market situation.
My bike has almost 44000 km on it and I have had literally 0 issues with it. Although I bought mine new and always kept up with maintenance. I think that a well maintained wr should not have any issues to get up to 80000 km and beyond. However buying a (fourth hand) almost 9 year old machine is always a gamble in my book.
Do you have an experienced rider friend who could look it over? or bring it to a shop for a check up?
As Diamond said, if you have no better option I would also consider it.
Let us know how it goes!
