Weight is a problem for EV motorcycles and EV's in general. I was recently looking at the Zero SR/F as a replacement for my Empulse if/when it breaks and is unrepairable (thanks Polaris). The Energica line of bikes caught my eye now that they have really chopped the price which is now comparable to the Zero. It's really hard to find the actual weight of these things but my jaw dropped when I found the Energica Ego sport bike checked in at 569 pounds--that is getting into Goldwing territory. Looking at it, I can't figure out where all the weight is. Also, Although it has 35 more horsepower than the Zero I doubt it can be very different in performance as it weighs nearly a 100 pounds more. In addition the extra weight and smaller battery pack should really tip the range scales to the Zero. In reading ride reports and watching videos of the Ego, the weight along with a high center of gravity really makes it a bear to drive in anything but a straight line. I am going to get one for a 24 hour demo this weekend so I will actually see what it is like. So, in regards to the livewire, the weight isn't off the scale but close to it. I never thought that the Empulse was a "lightweight" motorcycle but in this world, it is. I think the Empulse was and still is one of the best electric motorcycles ever made.
