Maybe I'm an odd case, but the Zero is perfect for what I use it for. I'm in a 3 season riding climate, and I don't depend on the SR/F as a primary mode of transport. It is my only motorcycle. My primary daily driver is a dually truck that runs on diesel. My SO has a daily, and then between the two of us we have a few fun cars. I ride the SR/F as much as I can when its warmer out. DC charging was actually a turn off for me. I live in an area where there are 3 DC stations in a 100 mile radius. Maybe thats changed since Harley dealerships had to put them in. Is 6kw charging super convenient? No its not. But the 3kw charging on an Energica would have made the bike non-usable for me. 6kw makes is tolerable, being able to dual j-plug at 12kw would be nice, but wouldn't change the way I use the bike much.
I use the bike primarily for commuting to work. But because I don't like to get the truck out for short trips, I also use the SR/F for any errands that I can fit in a backpack. Sometimes I ride to the next big city over where the dealership is, which is 65 miles away of mostly 75mph interstate. I know when I make this trip that its going to take extra time to stop and charge. And there is a slower route I can take that keeps me closer to 55 most of the way. Its about a $30 trip if I use my truck. Since I can charge for free, the round trip costs about $1 on the SR/F. But its also keeping wear and tear off the truck.
I don't do big touring rides. But I will go out for a few hours on a nice night and ride around. I can stop any number of places to relax where there is a charger and let the bike top up for free. If I'm not in the mood to mess with charging, I'll take a fun car out instead. My point is that I'm not trying to force the bike to be something its not. And I'm not upset that I can't use the bike 100% of the time. I knew when I bought it that it had specific use cases and that there were things I wouldn't be able to do with it. I love the bike. I love it so much its sitting in my living room over the winter.
Saying its rubbish because it doesn't have DCFC is a bit short sighted. It might not fit your use case. Thats fine. It fits someone else's. And I'd venture to say that with how many SR/F's they sold that DC charging wasn't the end all for a lot of people. Even with their 20kw battery, I'm not hearing that Energica is backlogged for 6 months. I don't see Livewires flying out of the dealerships. And Lightning - I guess we'll see how all that shakes out. I'm not saying anything bad about the other brands. If my geography was different I'd have looked at Energica and Lightning. And in 3-5 years I might. I didn't buy the SR/F thinking it would be the last bike I ever buy.
I'm excited that they are coming out with a sport bike. I kind of wish that they offered the fairings and the wind screen as an accessory option on the SR/F.
