Once Energica updates their batteries, it will be a no brainer for those with the cash. DCFC and a 13-15kWh batter? Forget about it.
I agree with you Steven. But only because of those getting it have a high disposable income, and perhaps already have another Zero electric motorcycle or others. Getting service done to these things is going to be a nightmare. Because of the voltage of the pack, there will likely be only one service center in the US. IIRC Insurance premiums go up a million dollars per shop (edit: correction I think I remember hearing the policy goes up $100,000) working on anything DC over 150 volts, because a technician who makes a mistake doesn't get a spark and a burn, he never will know what happened, and that comes with a high cost. This is the main reason you wont see Zero going to a voltage like that any time soon. You'd have to sell a lot of bikes at $1500 profit to justify spending an extra $100,000 per year on insurance. Perhaps the US won't get a service center after all and all bikes will need to be shipped to Italy for anything involving the battery pack, motor or controller. I know in Europe all the Energicas that are breaking are having to be shipped to Italy for repair.
So not only that there wont be service centers close by, but the number of road tested miles on these bikes total might match what Zero had in 2012. There are growing pains and things that might fail that haven't even been discovered yet. They might only have like 100 or 150 of these bikes ever built. Being an early adopter of one of these will need to be someone who can be totally ok with the bike breaking and needing months to repair.
While Steven had an issue with his 2015 that is bad, and another guy Tony Kalneiv in Thailand also had a big issue with his 2015 Zero, but other than that since 2015 the bikes have a pretty amazing reliability if you don't count the onboard charger. The 2016 was even better and I don't think this whole year I've heard of anyone with a 2017 with any issues. A 2018 Zero should be pretty bullet proof by now I would think as they keep refining it without changing too much.
If you have unlimited money, get the 2018 Zero SR and the Energica. Ride the Energica till it breaks and then ride the Zero.
But if you only have $40,000 to get the Energica, I would say get the Zero instead and save the $20,000 to spend on something else or to get a 2nd 2018 SR for a friend to borrow and ride with you. Because the bikes are pretty close. Energica is just a hair faster, not by much, but the Zero can have 50% more battery 11.7 kWh for the Energica vs 18 kWh for the 2018 Zero. I think when you consider everything getting the Energica doesn't really make sense unless you get both.
