2021 Zero SR/F Totalmotorcycle.com Key Features
THE UNPRECEDENTED COMBINATION OF INDUSTRY-LEADING POWER, CONTROL, AND CONNECTION. RAPID CHARGE SYSTEM
Our all-new scalable Rapid Charge System allows the bike to be configured for 3 kW, 6 kW, 9 kW or 12 kW of charging at any standard Level 2 charge station.* The SR/F Rapid Charge System will be able to charge at 38 miles of range per hour of charging (mphc) on 3 kW, 76 mphc on 6 kw, and 153 mphc on 12 kW which can recharge the battery pack to 95% capacity in 1 hour of charging. * Note: SR/F requires use of included EVSE cord in order to charge on a standard 110 V wall outlet.
POWER PIVOT
A proprietary concentric motor and swingarm pivot design provide the optimal architecture to ensure constant drive-belt tension and maximum torque delivery to the rear wheel. A custom-designed, large-bearing swingarm pivot allows ample space for the high-performance motor while allowing a slim chassis waist to enhance rider ergonomics and bike maneuverability.
CYPHER III
Cypher III, Zero’s proprietary operating system acts as a hub to integrate all motorcycle systems. It delivers precise performance seamlessly for a consistent and superior riding experience.
ARSENAL OF RIDE MODES
THE SR/F’S ARSENAL OF RIDE MODES ALLOWS THE RIDER TO CUSTOMIZE THE BIKE’S PERFORMANCE THROUGH THE INTUITIVE NEXT-GENERATION APP AND DASH INTERFACE. THE SR/F NAVIGATES THE ROAD NO MATTER THE CONDITIONS WITH STREET, SPORT, ECO, RAIN AND UP TO 10 PROGRAMMABLE CUSTOM MODES.
BOSCH MOTORCYCLE STABILITY CONTROL
The SR/F is the first electric motorcycle to integrate Bosch’s MSC System, renowned for dynamic acceleration and improved stability regardless of road surface or conditions. When combined with Cypher III, the MSC’s full capabilities are unleashed, resulting in best-in-class straight-line ABS and cornering brake control, traction control and drag torque control.

ZF14.4 BATTERY PACK
The ZF14.4 lithium-ion battery makes the SR/F capable of a 200-mile maximum range.* The battery’s industry-leading power and energy density combined with an aluminum heat-sink housing and thermal transfer interface ensure consistent cell cooling and maximum long-term powertrain performance. * Note: Maximum city range includes addition of Zero’s Power Tank, available March, 2020.
ZF75-10 MOTOR
The ZF75-10 motor delivers 140 ft-lbs of torque and 110 hp, effortlessly propelling the SR/F to a top speed of 124 mph. Pairing Zero’s renowned internal permanent magnet brushless architecture and a passively air-cooled compact design creates class-leading performance and efficiency.
CHASSIS
Incredibly light. Unbelievably strong. The steel-trellis frame, custom swingarm and advanced Showa suspension deliver an athletic and intuitive riding experience. The powertrain is perfectly distributed, resulting in a weight-optimized/mass-centralized design, while a dual radial front brake system makes shedding speed as exhilarating as building it.
