Just to clarify the speculation regarding colors...
These are all Engineering test bikes, so we swap body panels back and forth as needed. It could be that we are testing a different color scheme, finish (gloss vs. matte. vs. textured, etc...), or material (carbon fiber, ABS plastic, polycarbonate plastic, etc...) OR we just grabbed whatever part was on hand to get the bike on the road.
From what's been photographed, the only "standard" bike is the last black bike, which accurately represents a black Empulse R. The white bike is an Empulse base model (hence the black forks) with the fenders upgraded to the carbon fiber units from the R. The other "black" bike with the red rim tape is our data acquistion bike and actually features almost all carbon fiber bodywork (which is why the tank looks black). The red rim tape is an accessory item and is very easy to install. Some love it, some hate it, so we'll leave it up to the customer to decide whether to add it or not. For the astute with a keen eye, you'll probably be able to pick out other accessory items being tested in the coming months as we release these kinds of photos (most of the time unwittingly) over social media.
Since I've now got your attention... I'll just add a sincere "Thank you" to the members of this forum that have stuck it out while we met challenge after challenge to launch the best electric motorcycle in the world. The common theme from everyone that's been on it so far has been... "Exceeded my expectations!". That makes it all worth it...
