My concern with the H-D separate EV branding plan is that the cost of setting up a dedicated dealership from scratch is very expensive. It just won't work unless H-D bankrolls the entire operation from start to finish, including operating costs. Financially, it would be a lot better for them to set aside a specific area in established H-D dealerships to market their electric models and have dedicated salespeople, parts staff and technicians that would provide customer service for the electric bikes. Trying to develop stand-alone EV dealerships, especially when the market for electric motorcycles is so small right now, sounds like a recipe for financial failure. And you know how the H-D board hates financial failure.
Finally, a few established motorcycle manufacturers, like Yamaha with their Star cruiser brand, have tried to create separate premium or unique sub-brands and I don't believe that has ever worked out in the long-run.
