I see that Zero is calling the SR/F a 2020 model, while the
Motorcycle.com article claims it is a 2019 model. My guess is that calling it a 2020 bike will be the official model year. That is what BMW tends to do at times. As an example, my 2016 BMW R1200RS was bought by me in May 2015. When introducing a brand new chassis, it appears to be typical for vehicle manufacturers to sometimes jump a year into the future.
My guess is that the new SR/F platform will start to supersede the old 2013-on chassis when future models are introduced. It certainly seems like a worthwhile upgrade to the previous chassis, although some of the premium components of the SR/F will likely have to be cut back to keep the price of future models under control.
If you ask me, the SR/F really takes the wind out of the LiveWire's sales. $10K less and it appears to have more premium features. In particular, I do like those Bosch traction control, cornering ABS and cruse control features. Plus, the smart phone system seems pretty complete - although likely more than I could master.
I must say that I am very impressed with the new model. But it is definitely overkill for my utility and transportation usage.
I also like that it's weight is about 100 pounds less than the Energica models. For me, that would be a big plus.
