I have no idea if Harley has or had a real wholesale parts program similar to the auto companies, but if they do I could possibly see them adding restrictions just like they recently did on third party internet sales and other similar stuff. I'm sure you all remember all the posts about how they were trying to eliminate all the ebay stores and advertised discount prices on part and accessories. This could just be this particular dealer's reaction to some of that. Or it could also be as noted earlier, just this dealer reneging on a previous business agreement with this indy and laying it off on Harley as an excuse.
BTW, certain dealerships seem to be pushing the 20% discount business even harder after all the talk about Harley supposedly putting a stop to it. American's, even franchisee's, don't take well to being told they can't do something that they've always done in the past. I don't think I'd let this report keep me awake at night.
