Great question skuzzle.
Brammo's engineers must be hard at work on something. The 2014 Empulse changes, while non-trivial, don't really feel like they engaged all of Brammo's engineering efforts.
So things in the skunkworks:
1. Brammo has pretty much removed the dirt bikes from their site. Perhaps they could revisit these? The prototypes Brammo was showing appeared to be nearly identical to the SMRE prototype dirt bikes, I get the feeling at the time that they were not a huge priority.
2. Turn BrammoParx into an animatrionic amusement park, complete with wheelie machines and dinosaurs. (A happy dinosaur is a dinosaur that doesn't have to get turned into oil, little Timmy!)
3. Build a damn touring bike.
I vote for #3!
