Speaking from experience, maintaining a Triumph Dealership isn't for everyone. Especially when a particular dealer isn't agreeable to the "preferred" way of doing business.
One of the common dilemmas is brought about successful dealers with large floorspace. In other words, selling several brands under one roof. It is business model that puts less emphasis on any single brand, and more on dealership/relationship.
My local Harley Dealership doesn't move a tremendous amount of bikes, but the facility is amazingly huge. On any given Saturday, the lot is full of bikes and traffic for many hours and the cash register is going non-stop. However, the shops closeby (Polaris/Victory, Yamaha, Suzuki, and Honda) are left negotiating with those who want to come in and price-shop an already low-margin motorcycle.
Competing Dealers may not have the brand recognition, but they can build cool places to attract almost the same crowds and staff them with equally impressive folks and goods to sell. This creates a flexible atmosphere that is easier to manage (from a profit margin perspective). Business Lenders like it as well because it spreads the risk.
The problem with that is it does little for brands like BMW, Ducati, or Triumph. Sales and Customer Satisfaction is historically maximized when the respective dealer is committed to the brand and is willing do what is necessary to compete - which is a tall order for any brand that doesn't have a significant percentage of the market.
Dealers are people too. They want to be successful and supportive of their families just like any other business owner. Triumph North America is like any other distributor, they want to have a well-oiled network of successful dealers with as few "problem dealers" as possible.
The end result is an economy where the only business ventures worth doing are those with practically a 100% chance of success; which translates to something that is not complicated - the partnership isn't for everyone.
It does impact owners who are accustomed to accessible dealer support. We have been without a Triumph Dealer in my area for eight years, but strangely many of my friends have gone back to Triumph and work with a dealer three hours away. I'm the only holdout in our local group, but who knows
