Hi, I am Sjerp, living in the Netherlands. Very nice review! I own an Energica EsseEsse9 since April 17th, which I ordered early December. I have done 600+ miles in a week and before I got the Esse, my dealer lent me a 2017 Eva for a month, on which I did 1900 miles. I have tested a 2017 Zero SR for two days commuting, just as a BMW C-evolutiuon a year earlier. Before electric, I have been driving a BMW 1150RS for 8 years.
I almost ordered a 2018 Zero SR with charge tank and luggage kit but decided to visit the Energica dealer (who also sells Zero) to compare the deal. I then learned that the Eva was actually not that much more expensive* and had CCS charging (3x faster than Zero with new charge tank), a total game changer. After the two days test, I was convinced, not so strange though, as a BMW driver.
I underline the power consumtion difference: I have the impression that the Zero is a bit more economical, probably a combination of drive train efficiency and overall aerodynamics (Eva is also wider). With the Eva staying below 10kW/100 km is a challenge. For my commute (38 miles) not a problem at all. With 60-80mph travel, I always arrive at work with 40-48% battery left. With heavy traffic, I can manage 50%.
On the first meters, I have the impression that the Eva 80kW acceleration is a match with the Zero SR. The Eva has a more delicate launch. At mid-speed Eva pulls much harder.
Again, very good review of the Eva 107. If there are questions regarding the EsseEsse9, I'm happy to open a topic.
*Edit: end of 2017 my dealer started lowering 2017 Eva prices. In EU, now a 2017 Eva is cheaper than a 2018 SR with Charge tank.
