2025 Zero SR/S: Technical data, Features, Design, Price.
The 2025 Zero SR/S electric motorcycle is one of the models produced by Zero Motorcycles, featuring a full fairing inspired by advanced aerospace design.
Design
This design not only offers the motorcycle aerodynamic elegance and a stunning profile, but also significantly improves its highway performance and range—13% more than the award-winning SR/F model. The SR/S combines comfort and style with a more comfortable riding position, making it an excellent choice for long journeys. Equipped with the Cypher III operating system, the SR/S offers smooth control and all the essential features, making every journey unforgettable.
Battery
The Z-Force’s 17.3 kWh lithium-ion battery allows the SR/S to travel up to 116 miles around the city on a single charge. The option to increase the range to almost 21 kWh is available through the Power Tank option (service installation required). This battery offers industry-leading power and energy density performance while delivering consistent cooling performance thanks to its aluminum heatsink casing and efficient heat dissipation. This ensures long-term transmission performance without the need for regular maintenance.
Charger
The fast charging system for the 2025 SR/S consists of a standard 6.6 kW charger, providing efficient charging at a variety of levels. For those seeking even faster charging, a quick charging module accessory is available that increases onboard charging power to 12.6 kW. Additionally, you can use the included EVSE cord to charge the SR/S from any standard 110V outlet, convenient for overnight charging.
Motor
The Z-Force 75-10 engine found on the SR/S model produces 140 lb-ft of torque and 113 hp. This engine propels the bike effortlessly to a top speed of 118 mph. It uses a brushless design with internal permanent magnets and a compact layout, delivering best-in-class performance with passive air cooling.
Chassis
The SR/S features an exceptionally light and robust steel trellis frame, a custom swingarm, and an advanced Showa suspension for sporty, intuitive handling. The weight-optimized powertrain design is perfectly distributed, and the dual radial front braking system makes both acceleration and braking a pleasure.
