Look at MCN and fleabay plus fleabay completed sales The dealer prices will be higher but then they have to warranty the bike Keep in mind that it's the back end of the season for most riders (dons tin hat) So less buyers about Also consider selling without panniers
At that time the lower mileage would bump the price up. But this time of year expect to knock £500+ off the price because there are fewer buyers about than in spring.
I was trying to sell my shiney 2009 with brand new tyres, 12 months tax, 12 months MoT, Full service History, Panniers, Top Box, £1000 of brand new Nitron shocks, Fender Extender, Mudsling blah blah. Got no enquiries at all for £7.5K...and it was at the beginning of the season!
I got no interest in my only just 2 year old 12 plate 1200GSA with all the trimmings ESA etc and with a massive 15k on the clock a couple of months ago for £9k so PX-ed it for the same amount to a dealer they then added £3k and put it on the forecourt sold a couple of weeks later
Dealers are selling them by offering private is just not happening at the moment
