Zero is putting the electric motorcycle world on notice with the 2020 SR/S, a re-engineered step up from the outgoing model that can go up to 201 miles on a single charge. The SR/S can go 40 miles longer than the previous SR/S and 50 miles more than the upcoming Fuell Flow — no small feat. What makes the SR/S capable of these range numbers is the optional Power Tank, but even without it, you'll see 161 before needing to recharge. Recharging is fast too, with 0-95% coming in two hours on a normal charger. The SR/S doesn't take any steps back in performance either, with 110 horsepower instantly on tap and a top speed of 124 MPH. The new SR/S will go on sale in early March.
