This is part of a discussion I've been having for a while now, but my focus has been more about "how long before the big manufacturers get into the market" rather than a buyout of Zero. For my money, what with Polaris' moves, I'm predicting 2016. The timing of my book was due, in a big part, to that belief. That said, I'm thinking one major mfr, not a bunch of them.
Harley? Fuggetaboutit.
Really, though, the thing anyone has to understand about the big boys is that they're looking for astronomical sales numbers, by electric motorcycle standards. Energica's Livia Cevolini has told me she's looking for 500 units sold for their first model year. I'm not entirely sure, but I'm under the impression that Honda is looking for a couple of more zeros on that number before they consider it.
Speaking of Honda, every time Mugen races we get back into that discussion. Honda clearly is toying with R&D, and Zero is doing them a huge bit of free market research, but buying them out? They don't need to, I doubt they want to, and consolidating the market at this stage isn't going to do anyone any favors in terms of selling 50,000 units a year.
I also think it's important to understand that Polaris bought out Brammo at fire-sale prices, basically due to very low delivery of sales predictions. In a lot of ways, it can be seen as cutting their losses rather than trying to enter the market in any real way.
I think I need more coffee - did that make sense?
