Effortless control

As much brains as brawn, the SR/F ensures the rider is in control regardless of conditions thanks to Zero’s new Cypher III operating system and Bosch’s Motorcycle Stability Control (MSC).

Cypher III acts as the central hub, integrating all systems on the motorcycle to deliver a superior riding experience. From Bosch’s MSC all the way to Zero’s next-gen app and dash, everything is seamlessly connected for easy and intuitive 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 lIl, 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.

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.

The SR/F is also equipped with a dual radial front brake system, adding a level of control that makes shedding speed as effortless as building it.

Effortless connection

The SR/F is the first fully “smart” motorcycle thanks to the Cypher III operating system. It is also the first commercially available connected motorcycle on the market. 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.

Bike Status & Alerts

The SR/F alerts customers regarding bike status including interruptions in charging and tip-over or unexpected motion notifications. In addition, the “Find my Bike” function allows riders to keep tabs on the motorcycle at all times.


The SR/F takes the convenience of recharging to new levels with the ability to remotely set charging parameters including Targeted Charge Levels, notification of State of Charge (SoC), Charge Time Scheduling and Charge Tracking. These notifications allow riders to control all aspects of charging and to monitor charge status even when away from the motorcycle.

Ride Data Sharing

Riders can gather, relive and share extensive data about their ride through the app. An industry first, the motorcycle records bike location, speed, lean angle, power, torque, SoC and energy used/regenerated. Riders can replay each ride and also choose to upload additional content to record and share their full experience. Riders also have the option to keep data anonymous.

System Upgrades and Updates

New updates and diagnostic capabilities allow the rider to remotely download the latest Cypher III operating system release to ensure optimal performance and provide access to feature improvements.

All the benefits of connectivity are offered for free for the first two years with the purchase of a new SR/F.
