Can't say I'm surprised about Buell. Eric Buell is a very intelligent person but I believe his motorcycles are largely an answer to a question no one asked. He hung his hat on some very specific design principals that were not quite mainstream. At best Buell was a boutique or niche market brand. It just couldn't generate the numbers The Motor Company needed.
As for the MV acquisition, that never made sense. Although, if I wanted a real sportbike, it would have to be an MV F4.
H-D is on one hand hobbled by its own success. The market expects its products to fit a very traditional mold. Their history is punctuated by a number of decent alternatives that just were not "Harley" enough.
And, for what it's worth, the Company is still paying dividends to shareholders.
