The shop local to me quietly dropped the brand too. Now Suzuki and Honda only. Just a couple of years ago, they had boutiquefied the HD side of their shop, and crammed the other two in a space about 20% of its size, Almost as an afterthought. This was no doubt done at the request of the mothership.
TheY seemed to be doing ok, as did the other NB shop that is closing (There will only be one dealer left in NB).
Looks like HD wants fewer dealerships on the balance sheet, they are probably seen as liabilities, and not attractive to potential equity firms.
Funny anecdote on my local HD shop: I went and test rode a bunch of them when the road show rolled into town. I was still Riding the wheels off my thousand dollar C10 Concours at the time. Of all the people who also rode their bikes there, I had the cheapest bike by a factor of ten. On the other hand, I had the most expensive helmet, also by a factor of ten (an Arai). I also ruined the group photo for seven out of the eight outings (I missed one at lunch) with my high viz riding jacket. Guess which one was on their website...
