New dealer stock 2015 Versys 650 ABS are available for $6300, averaging $7400 online But the average price for a used one is around $5300, dealer, asking. I think your best bet would be to remove all the farkles and sell them independent of the bike. Sell bike for $5000, extras for another $1000. As is I don't think you'll get over $5500 for the total package.
Keep in mind these are the words of someone who does not seek, love, hate, or covet the bike in question, just poking around for 3 minutes on the internet. But, I tend to be fairly close in my random valuations.
Rationale, my first thought when looking at your pictures is having all the bags on the bike makes it look like an old man bike, unappealing to the younger generation, especially the tail bag. However, as an adventure rider I think, man, those are some cool bags and racks. I'd like to buy those for my bike. So, market to both customer bases and maximize revenue.
