So I stumbled upon this article today. Seems like Yamaha is getting ready to swoop in and not let Alta take all the electric money. I know this article is just referencing that Yamaha is just getting ready to put these bikes in Japan but if production is not that far off it seems they can come in to the U.S. with these bikes rather easily.
"Apparently the company recently made arrangements with Saitama City in Japan to promote electric motorcycles and businesses around them, indicating that production is not far off. The campaign, titled the E-KIZUNA Project, will promote the electrics as practical solutions to urban issues like traffic congestion, parking, and pollution. One of the key elements in overcoming public resistance to electrics is the bikes' swappable battery packs, since the foremost concerns among potential consumers have been limited range and slow charging times."
