This is one of the things I bring up frequently. I don't openly spam the video review I did on the SR/F because I'm not looking to bash Zero. Another thing I'd mention is that, while belts are awesome and low maintenance, Zero tends to under-spec their belts and they get shredded under heavy torque.
I checked a couple of NEW belts on NEW bikes at the dealer in Reno and they were way too tight. I wouldn't even ride those a mile. I would expect the belt to break. I wonder if them being over-tightened is the main reason the belts to break--especially on the new bikes.
Is it the dealer or Zero who installs the belts?
But yeah, compare my Harley belt to any Zero. But I wonder what effect a thick belt like Harley uses will have on the range of an electric motorcycle.
Every time I see a small bump on the road (or something like a train track) I always back off the throttle a bit on my Zeros.
Anyway, I would say my Energica is my favorite bike to ride, and it is a SS9-. However, Zero has it's advantages also. Less maintenance, lighter.
I own both and where I am going is what makes me decide which to take. The type of charge stations where I am going. I can charge my Zero SR with 8 KW on the road from some J-plugs (but some J-stns cannot go that high). But that is still better than the 3KW AC charging on the Energica. But if there is CCS, then it is 24 KW on the Energica.
I would decide which bike to buy by the charge stations in route of the places you want to go.
I have found J-1772 to be better in Reno, but CCS to be better in CA. But it depends on where I am going. Between here and Reno, it makes no difference as there are plenty of both types, no matter which way I decide to go. I-80, US50, and Hwy 20 all have all I need between here and Reno of either type.
Anyway, I would decide by charge stations. Zero is better for J-plugs, but Energica has CCS.
I was on my Zero SR for most of the day today. I really have no complaints about either make of bike, but they are quite different.
IMO, Energica would be the perfect bike if they could squeeze a 6KW AC charger in there for the places that don't have CCS. And a lot of J-charging is free. Especially in Reno.
The service from Energica I never hear anybody complain about. But Zero has a lot more dealers--but way too many issues from most, from what I read here.
It can be a tough decision to decide on one or the other. But I think the type of charging where you will be riding could be the biggest issue.
Another plus on the Energica is it comes with a reverse.
