In Minneapolis, in Jan, when snow isn't arriving very fast locally or in many mountain areas, new sleds will be unveiled next month, etc., $9k ish - based on what i see for sleds being put up for sale, and watching some to see when/if they actually sold, etc. If you want to sit on it for a while and hope for more, you might get more, but the gamble is always, "how badly do you want to sell it" and when. What missing is the regular reports of big snowstorms. That would really help keep the values higher for another few weeks.
Specific to your shocks, if you have the originals, put them back on and sell the X1's separately. You will get more in total, than if included on the sled. (After a motorcycle dealer asked me "how much did you spend on aftermarket stuff that you wont get back in resale [and my heart sunk], I realized how true that statement really was)
Back in Nov/Dec when everyone's hopes were for snow to start early like last year, you could have found at least $1k more.
My observations, only. I suspect if being in a mountain region, you might see bigger numbers, too.
Good luck !
