Zero SR

EFFORTLESS POWER
The Zero SR was the first R-type variant of our groundbreaking Zero S, and the 2024 SR continues the heritage of charting new territory. The 2024 SR is the middleweight in the Zero naked street category and it’s the only motorcycle ever to be able to truly change with its rider. Available stock as an A2 licensed machine, the SR comes with an impressive 140 N-m of torque and 52 kW of power. The SR is also upgradable via a dealer installed firmware update that turns it into an even more capable full ‘A’ licensed machine, provided you meet the updated licensing requirements. The full A SR delivers even more exhilarating rides and produces 166 N-m of torque and 64 kW of power. Regardless of which rendition of the SR you ride, it has entirely improved capabilities over its previous version thanks to a new battery, a whole new style, and a new motor. All of this plus the award-winning Cypher III+ operating system means that the SR occupies a truly remarkable tier in the Zero naked street product line.

Z-FORCE 75-10
The 2024 SR uses the Z-Force 75-10 direct drive motor making it the most powerful SR to date. More than just the powerplant that drives the SR to transformational rides, the 75-10 motor also is designed to be structurally load bearing which eliminates excess weight and improves ride quality and balance. All this along with Zero’s renowned internal permanent magnet, brushless architecture, and a passively air-cooled, compact design delivers class-leading performance and efficiency with virtually no maintenance required.

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.

FARTHER FASTER
The Zero SR is powered by the revolutionary Z-Force 15.6 kWh power pack—the largest stock battery capacity ever for this model. Capable of delivering up to 253 km of city riding stock, the SR is also compatible with range-boosting accessories available by installation at your local dealer. Featuring proprietary battery chemistry, Zero's Z-Force batteries boast industry-leading energy and power density, setting new standards in the automotive world, all while remaining fully recyclable. Experience unmatched performance and endurance with Zero's cutting-edge battery technology.

EFFORTLESS CONTROL
Just like all models in the Zero naked street product line, the SR is equipped with Zero’s latest Cypher III+ operating system and outfit with cutting edge performance features already included. Bosch’s Motorcycle Stability Control (MSC) is equal parts brawn and brains. Effortless power is paired with intuitive control, creating the new standard for premium performance—an adaptable motorcycle and powertrain combination that navigates diverse road terrain and conditions, effortlessly.

CYPHER III+
The absolute gold standard for electric motorcycle operating systems, Cypher III+ is the conductor behind the symphony of instruments propelling the 2024 SR. This foundational technology is what makes it possible for riders who achieve all requirements for upgrading their A2 licenses to full A can do so without having to replace their motorcycle. Simply visit your local dealer and you can have a full A performance feature added to your SR for even more power, torque, and possibilities. The SR is infinitely customizable and fully equipped with a barrage of Cypher Features. Elevate your ride with the ultimate riding experience.

ARSENAL OF RIDE MODES
The SR’s arsenal of ride modes allows the rider to customize the bike's performance through the intuitive NextGen app and dash interface. The SR navigates the road no matter the conditions with Rain, Eco, Standard, Sport, and Canyon modes pre-loaded and a virtually infinite number of custom tuned ride mode adjustments available.

EFFORTLESS CONNECTION
The SR is not just connected but truly "smart" with Cypher III+ OS and OTA updates. Customize the dash, access the NextGen app with standard features, and enjoy limitless possibilities. Futureproof intelligence and unmatched power make the SR the ultimate ride with seamless connection in every detail.

THE CONNECTED BIKE
The SR is connected through cellular networks, transmitting info to the NextGen app at all times. The app offers access to a host of ride information including current bike status and location that are always available. This connectivity gives the rider the ability to monitor the bike in four main areas: Bike Status & Alerts, Charging, Ride Data Sharing, and OTA System Updates.

ADVANCED APP
Zero’s next-generation app works with the dash and Cypher III+ to create a feature-rich ecosystem. Features in the app include ride mode selection and creation, personalized dash options, scheduled and target-based charging, and so much more.
