"I don't see Zero selling many cruisers if they offered them. The people buying cruisers will never give up their exhaust notes and manual transmissions either."
Agreed; there's probably not a motorcycle market segment less likely to adopt electric than the traditional cruiser segment. That's a market that's defined by perception: appearance of the bike, sound of the bike, and brand of the bike. 90%+ of the cruiser market (in the US, at least) is so averse to anything removed from those criteria that they wouldn't even buy the v-rod. If water cooled and low slung from HD doesn't get bites, nothing else will. Silent, electric, and no transmission? Non-starter for those folks.
And the tech isn't yet up to par for the vast majority of the touring segment. Even with a range of 300+ miles you're not going to get bites from those guys until you're looking at 10-15 minute charge times off of any 110V household outlet. I love my FXS, but I absolutely would not have bought it if I didn't already have an ICE bike in the stable. Great for my 40 mile commute, great for quick errands, and superb for screwing about on backroads, but if I'm headed anywhere involving real distance or carrying anything weighty, I'm hopping on a gasser.
