My suspicion (and hope) is that they're very busy in development and testing right now, and possibly keeping mum about some changes until they can definitively talk about them. Brammo (and in particular, BrammoBrian) have been pretty open about the development process to this point, including sharing some tasty RR video.
Of course, Brammo doesn't exist in a vacuum, and other competitors are moving in on this space pretty quickly. Honda's EV-neo is the first hint towards electric two-wheelers from one of the large traditional manufacturers, and while the EV-neo's battery tech (toshiba SCiB) won't get them to 100+ mile ranges right now, they have the resources (if perhaps not the corporate will) to massively expand development if batteries and consumer interest merit it.
I'd love to see more Brammo updates on the RR and racing schedule, on manufacturing, and on changes to the production-intent designs.
Jay: The Brammo Enertia Plus strikes me as more of an urban assault EV than the Empulse.. it's significantly lighter and narrower, and it's still an open question (IMO) if it'll be faster than the Enertia 3.1. I don't really think I'd need to go faster than 60 mph in an urban environment, too.
