Hard to believe its so low mileage, judging by the general condition.  The clocks are in Km too, so in fact it's actually reading under 6000 miles!  
 
 Damaged cans/non-original footpegs?  Maybe it's spent time on the track?
 
 "Runs beautifully" doesn't say a lot - and that makes me wary.  I'd want much more info before bidding.  I'd want some good close-up pictures too.
