I did a test ride on the SR/F, I found it rather uncomfy. Foot pegs up too high and not adjustable. Riding position too sporty, need to lift head up a bit. But the performance was great, scary fast in sport mode.
I am very happy with my 2020 Energica Esse Esse 9. Very comphy, no need to change anything. Charges to full in minutes on CCS (@25KW) and can still use J1772 (@ 3KW) or even 120 VAC (@1.5 KW) with the adapter it comes with (that I have never used). I also find the reverse to be handy. It also has a slow forward where 1.75 MPH is WOT. I purchased mine from CA Moto BMW in Mt. View and had them deliver it to me in Auburn.
You may find yourself unpumped about the Zero SR/F if you try out one of the Energicas.
