SR/S TECHNOLOGY Inspired by cutting edge aerospace design, the new look of the SR/S is rooted in its all-new aerodynamic fairing. Like all things Zero Motorcycles, form follows function. When you lean into the cockpit and get behind the fairing you will be rewarded with a 13% improvement in highway efficiency and range with the SR/S versus its award-winning sibling, the SR/F. Sit up and you’ll discover a more upright and relaxed riding position that feels as good as it looks.TOP SPEED (MAX)124MPH, PEAK TORQUE140FT-LB, OPTIMAL CHARGE TIME 60MINUTES,  200 MILE RANGE With Power Tank, 100% ELECTRIC POWERTRAIN Low maintenance CYPHER III Operating system, 161 MILES City range, CLUTCHLESS DIRECT DRIVE Transmission, 516 LB Curb weight, BOSCH Motorcycle stability control, 31.0 IN Seat height, 5 YEARS/UNLIMITED MILES Power pack warranty*
