2010 bike in good condition with 38000 miles, R&G crash bars, serviced regularly at home, new discs and pads, never dropped, ECU flash at Hilltop.
eBay prices seem all over the place.
Sold my 11bike with hilltops magic last year for £5950
So I guess slightly lower than this, I had if I remember a few miles less than you.
Realistically I would say £4k to £5. You're probably better trading it in if you are buying another bike.
