If I was you, I would probably see if I could find a dealer with a new-non current '17; I'm sure they're out there. Although you may have to do a fly-n-ride. But, how many miles does your current ride have?
Good way to go if you can. Your '14 is barely broken in! I've learned my limitations on the S10 in rougher stuff. (The S10 is more capable than I am.) A lighter bike would be way more fun when the going gets rough.
I found a left over 2017ES with 0 miles in Jan. , hadn’t even been serviced yet with 4 years of YES for 11,900 plus tax , title etc. Dealer was ready to sell it because it sat on the showroom floor since new with no one interested in it in south Florida.
I found a leftover 16 es last August. It was a great deal. I just added 4 more years of YES for under $400. Only thing was I could have any color I wanted as long as it was black. They were selling the non es for $500 less. I went with the ES and haven’t regretted that decision at all.
