The Sora is a bit on the "portly" side of the scale
It is, it weighs about as much as my ZF9 + your XU combined : )
It's also got more battery capacity than the two of our bikes combined as well .. and a good 30% more than the Empulse R.
Cool bike. Not $40k cool. I'd buy a Lightning if I had that kind of money to spend.
Still, I hope they sell every one they make. There is a small market for very high-end bikes, and its build quality is right for that market. I hope they don't need to sell very many to sustain operations, however.
