Of course you're going to need to build less bikes when you have more competition. Harley is losing market share. There are more and more cruiser options each year. Plus, the 2nd-hand market right now is absolutely flooded with late 2000s models for dirt cheap compared to new models (Their resale value drop is starting to match other brands now).
If they wanna stay relevant, they need some major reform to attract a younger demographic, which means making non-cruiser bikes that aren't a normal Harley, or even Harley branded for that matter. Of course they are stubborn, so I don't expect anything drastic coming anytime soon from them.
The electric bike market does interest me though, I really looked into a Zero bike for a commuter. Some day, when the prices become more affordable, I can see myself owning one.
