The 2023 Zero electric bike models include the top of the sport bike line SR/S. The Zero SR/S has a powerful ZF75-10 motor that delivers an impressive 140 ft-lb of torque and 110 horsepower. It propels the SR/S to a top speed of 124 mph, effortlessly combining class-leading performance and efficiency. Complementing this powerful motor is the largest stock capacity battery ever made: the Z-Force 17.3 kWh lithium-ion battery. This beast of a battery gives the SR/S a maximum range of 227 miles. If that’s not enough, there’s also an optional 3.6 kWh Power Tank, bringing the total available battery capacity to nearly 21 kWh. The controller is a high efficiency and power dense, 900 Amp, 3-phase AC controller with regenerative deceleration.

The SR/S boasts an elevated design and its full-fairing gives it a commanding presence which sets it atop the ranks of American motorcycle brands. The bike’s trellis frame is wrapped tightly in the fairing, providing maximum aerodynamic efficiency and increasing the overall range by 13% over the naked SR and SR/F.

When it comes to comfort, the rider’s foot position is lower and the handlebar height is higher, resulting in a more upright and relaxed riding position. There’s plenty of room for a passenger, too, with lower pegs and a generous seating area. The suspension adds another layer of comfort and control to the ride, ensuring that you and your passenger stay planted on any riding surface.

The Zero brand of bikes includes the latest version of the Cypher operating system, Cypher III+. This system provides a suite of downloadable performance upgrades, enabling you to customize your riding experience via the all-new Cypher Store. The SR/S also comes with the Bosch Motorcycle Stability Control (MSC) system, offering improved stability regardless of road surface or conditions. The SR/S also comes with an arsenal of ride modes. Whether it’s Rain, Eco, Standard, Sport, or Canyon mode, you can customize the bike’s performance through the intuitive next-generation app and dash interface.

The 2023 Zero SR/S starts at $19,995 USD/$25,620 CAD

2023 Zero SR/S Features

The Z-Force 17.3 kWh lithium-ion battery makes the SR/S capable of a 365-kilometer 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. Additionally, the available 3.6 kWh Power Tank brings the total available battery capacity to nearly 21 kWh.

Our scalable Rapid Charge System allows the bike to be configured for different charging levels. Model Year 2023 SR/S 6 kW comes fully upgraded to 6.6 kW thanks to the included the Cypher Upgrade. In addition, you can purchase an additional 6 kw charging module (dealer install required) that can get you up to 12.6 kW. * Note: SR/S requires the use of included EVSE cord in order to charge on a standard 110 V wall outlet.

Customize your dash. Choose the bike info you want and see it clearly on the full-color 5” TFT display. Multi-mode navigation enables on-the-fly ride mode switching, cruise-control, heated-grips control and much more.

The Z-Force 75-10 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.

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.

The SR/S 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.
