The motorcycle market these days seems even more segmented than in the past and just finding a "standard bike" is difficult. For the most part, manufacturers build what people want to buy and these days it seems to be Cruisers, ADV bikes, and Bobbers. By comparison, the sport bike market is microscopic in spite of all the ink it gets in the enthusiast magazines.
Every Honda distributorship does its own advertising and often has its own accessories plus they have colors not available here. The NT's big lids came from Honda UK which is why they had to be originally ordered from outside the US. They were never ordered by American Honda although we did get the wind deflectors, gas tank protector, top box, etc, all of which were from Europe. There is no master plan for every accessory to be available in every country where Honda motorcycles are sold - that is decided by the sales people in those countries.
