Designed for city riding and short commuting, this model combines modern design, advanced technology, and powerful performance. In this article, we will look at the key technical features of the 2025 Zero S .
Engine and Performance
The Zero S is equipped with an advanced Z-Force® 75-5 electric motor that produces a maximum power of 59 hp (44 kW) and 80 lb-ft (109 Nm) of torque. The electric motor is brushless, AC, and air-cooled, which significantly reduces the need for maintenance.
Battery and Range
The model can be equipped with two battery pack options:
- Z-Force® 7.2 (7.2 kWh): up to 80 miles (143 km) in city mode and up to 45 miles (72 km) on the highway at 70 mph (113 km/h).
- Z-Force® 14.4+ (14.4 kWh): up to 175 miles (288 km) in city mode and up to 90 miles (145 km) on the highway at 70 mph (113 km/h).
An optional Power Tank module can be installed, increasing the range by 20-25%.
Charging
The Zero S supports three charging methods:
- Standard outlet (1.3 kW): A full charge from a standard outlet will take between 9 and 12 hours, depending on the battery capacity.
- Level 2 Charger (3.3 kW): Charging time is reduced to 4-5 hours.
- Quick Charger (up to 6 kW with external chargers): 95% charge in 2-3 hours.
Chassis and suspension
The bike is built on a durable aluminum frame with low weight, which improves handling and stability. The suspension includes a Showa 41 mm front fork and a Showa rear monoshock, which provide a smooth ride and comfortable riding on city streets.
Brakes
The Zero S is equipped with front and rear brake discs with a diameter of 12.6 in (320 mm) and 9.4 in (240 mm), respectively, with Bosch Gen 9 ABS brake calipers. The ABS system adapts to various road conditions and helps prevent wheel locking during sudden braking.
Electronics and controls
The Zero S is equipped with the Cypher III+ control system, which allows users to customize various motorcycle parameters, including riding modes (Eco, Sport, Custom), energy regeneration during braking, and other settings via the Zero Motorcycles app on their smartphone. An important feature is the ability to update the software over the air, which allows the functionality of the motorcycle to be improved over time.
Design and ergonomics
The Zero S has a modern and minimalist design with sharp lines and an aggressive silhouette. The seat is designed for a comfortable fit for both the rider and the passenger. The instrument panel is represented by a color TFT display, which displays all the necessary information about the motorcycle’s condition and riding parameters.
