2021 Zero Motorcycles SR/S NA ZF14.4 Standard

Effortless Connection

• Customize your dash. Choose the bike info you want and see it clearly on the full-color 5” TFT LCD display. Multi-mode navigation enables on-the-fly ride mode switching, cruise-control, heated-grip* control and much more.
• The SR/S is connected through cellular networks, transmitting info to the app at all times. Ride information, current bike status and location are always available. This connectivity gives the rider the ability to monitor the bike in four (4) main areas: Bike Status Alerts, Charging, Ride Data Sharing, System Upgrades and Updates.
• Zero’s next-generation app works with the dash and Cypher III to create a feature-rich ecosystem: • Ride mode selection and creation • Personalized dash options • Scheduled and target-based charging • Charge-station location assistance • Extensive notifications, including bike state of charge (SoC), time to charge and last-ride statistics • Remote query and notification • Ride data available for review and sharing: location, speed, lean angle, power, torque, SoC, energy used/regenerated • Remote diagnostics and Cypher III updates.

Effortless Control

• 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.
• The SR/S offers an arsenal of ride modes which allows the rider to customize the bike’s performance through the intuitive next-generation app and dash interface. The SR/S navigates the road no matter the conditions with Street, Sport, Eco, Rain and up to 10 programmable custom modes.
• The SR/S integrates 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 cornering brake control, traction control, and drag torque control.
• 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.

Effortless Power

• The ZF14.4 lithium-ion battery makes the SR/S capable of a 200-mile maximum range with the optional Power Tank. 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.
• The ZF75-10 motor delivers 140 ft-lb of torque and 110 hp, effortlessly propelling the SR/S 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.
• Our 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/S Rapid Charge System charges at up to 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.
• 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.

Elevated Design

• The full-fairing on the new SR/S gives it a premium look that commands attention from the passing lane to the parking lot. Wrapped tight across the bike’s trellis frame, it envelops a forward leaning rider in its cockpit for maximum aerodynamic efficiency and increases overall range by 13% over the naked SR/F.

Premium Comfort

• Thanks to lower foot position and higher handlebar height, riders will enjoy a more upright and relaxed riding position on the new SR/S. Its ergonomic comfort even extends to two-up riding, giving passengers the ride of their life with matching lower pegs and a larger seating area. The fine-tuned suspension adds another level of luxury to the ride.
