I see a taller, vented windshield, passenger floorboards, and backrest riser, and fog lights. Anything else ? and are you the original owner? Any factory warranty left? All these question help to determine the value. If you sell it outright, the price Mdbrock paid is decent. If your trading, forget trying to get any value. The dealer may give you 7-8k, because he wants to sell it for 12k.
Only 2100 miles on a 2015, and living in California? You gotta ride more, my friend!
