Honda won’t drop the MSRP on the 2017s. What’s in dealer stock is up to the dealer to decide a price. Actual sale prices vary WIDELY based on dealer style and motivation even today, and will continue to do so after 2018s arrive. You couldn’t put a finger on a price drop number, if any. It all depends on the buyer shopping around, and finding a motivated seller willing to deal.
Old stock of NC700Xs is pretty common. I often see 2 or 3 year old new models on showroom floors. CycleTrader currently shows 157 new 2014 and 2015 NC700Xs for sale at dealers in the US, and there’s even still 7 new 2012 and 2013 unsold models out there. It’s surely not like they’ll try to sell all the 2017s to make way for the 2018.
You might want to expand your shopping radius. I think one forum member from southern California went to Arizona to buy, and rode the bike home.
