<3 speculation : )
#1
EU requires ABS on all motorcycles > 125cc by 2016. Presumably this will also apply for the electrics, despite the lack of displacement. Brammo is probably a little early with ABS in 2014, but still very good to have.
Perhaps this is why you can't buy the Empulse in Europe yet .. Brammo may just be waiting until they can sell a ABS model.

Interesting @ updates to the motors. I suspect the Empulse will need the power bump to fend off a Size 6 Zero in stoplight racing. And of course the Energica, supposing it comes out in 2015, will be in a slightly higher power class and (probably) price class.
WHERE'S #3? WHAT SECRETS DOES IT HIDE D : Maybe a small weight reduction? Eh? Eh?

Brammo switched to Farasis cells for their RR bikes at Indy eRoadRacing, presumably 25Ah pouch cells. Reportedly Shane's bike was getting somewhat tired (it was originally Steve-O's bike, pack created for the 2012 race season) and it made sense to refresh both bikes.
Brammo currently uses 10Ah pouch cells in the Empulse, each module is 4s9p.
Suppose they swapped to the Farasis cells for the Empulse, probably in a 4s4p configuration. I don't have even approximate dimensions for the current cells Brammo is using, but it's possible that they could do this and retain their existing battery box or tweak it slightly, allowing them to retain the existing Empulse look with 7 battery modules.
Amusingly, this would give them the exact same logical battery configuration as Zero's ZF11.4 - 28s4p 10.0 kWh. (Brammo stacks their modules in series, Zero stacks their modules in parallel .. but the logical configuration is the same). Cell weight probably would go up slightly with the change, making an overall weight (or even holding steady on weight) more challenging.
With the same battery cell and configuration AND the same motor controller (Sevcon Size 6), then effective power truly would come down to tuning, cooling systems, motor size and gearing.
This is a ~11% bump in energy, which extrapolating out from the 2013 Empulse range would give it 134 city miles, 85 mixed miles, 62 highway miles. So perhaps slightly more for E1?
Assuming Brammo switched for the Enertia Plus as well, they would probably go from a 12s7p 70Ah module to 12s3p 75Ah.

Revised footpegs make a lot of sense. I expect we'll see clip-ons as a factory option as well. Perhaps E1 set up with original footpeg/handlebar configuration, R set up with racier footpeg and clipons?
