Powered by a Z-Force 14.4 kWh lithium-ion battery (nominal 12.6 kWh), the Zero S delivers a city range of 154 miles (248 km) and a high-speed highway commuting range of 101 miles (162 km). The Z-Force 75-7 air-cooled interior permanent magnet AC motor produces 68 horsepower (51 kW) at 4,500 rpm and 97 lb-ft (132 Nm) of torque, enabling instant acceleration via a clutchless direct drive system.

With a top speed of 104 mph (167 km/h) and a sustained speed of 81 mph (130 km/h), it's well-suited for mixed environments. Charging is facilitated by a 3.0 kW integrated charger, achieving 0-95% in 4.0 hours on Level 2, or 1.3 hours with the optional 6 kW Rapid Charger. The curb weight is 492 pounds (223 kg), aided by a steel trellis frame and Showa suspension offering 4.72 inches (120 mm) front travel and 5.51 inches (140 mm) rear. Braking duties are handled by Bosch Generation 9 ABS with dual J-Juan radial 4-piston calipers and 320 mm discs front, plus a 2-piston caliper with 240 mm disc rear.

The Cypher III+ operating system provides customizable modes (Rain, Eco, Standard, Sport, Canyon) through a 5-inch TFT display and the NextGen app for connectivity and updates. Starting at $14,995 MSRP, it offers economical operation with recharge costs around $1.60.

The Zero SR/F: Premium Streetfighter Performance

The Zero SR/F elevates the streetfighter category with aggressive styling and enhanced capabilities, appealing to riders who crave raw power and advanced technology for spirited street rides.

It features a Z-Force 17.3 kWh lithium-ion battery, providing a city range of 176 miles (283 km) and a high-speed highway commuting range of 117 miles (188 km). The Z-Force 75-10 motor outputs 113 horsepower (84 kW) at 5,600 rpm and 140 lb-ft (190 Nm) of torque, delivering seamless power through direct drive.

Capable of a maximum top speed of 124 mph (200 km/h) and sustained 110 mph (177 km/h), the SR/F excels in dynamic scenarios. An integrated 6.6 kW charger allows 0-95% charge in 2.2 hours on Level 2, reducible to 1.1 hours with the optional 6 kW Rapid Charger. Weighing approximately 498 pounds (226 kg), it utilizes a steel trellis frame with Showa suspension mirroring the S model's travel specifications. Advanced Bosch MSC with cornering ABS enhances braking via dual 320 mm front discs with 4-piston calipers and a 240 mm rear disc.

Cypher III+ enables mode customization and app integration, with added features like heated grips on premium trims. Priced from $20,495 MSRP, recharge costs average $1.93.

The Zero SR/S: Aerodynamic Sport-Tourer

The Zero SR/S builds on the SR/F platform with full fairings for superior aerodynamics, ideal for extended highway rides and touring while maintaining sporty credentials.

Equipped with the same 17.3 kWh battery (nominal 15.1 kWh), it achieves a city range of 171 miles (275 km) and high-speed highway commuting range of 116 miles (187 km), benefiting from a 13% aero efficiency gain. The Z-Force 75-10 motor generates 111 horsepower (83 kW) at 5,600 rpm and 140 lb-ft (190 Nm) of torque.

Top speeds reach 124 mph (200 km/h) maximum and 106 mph (170 km/h) sustained, making it a capable long-distance machine. The 6.6 kW charger supports 0-95% in 2.2 hours, or 1.1 hours with the optional upgrade. At 518 pounds (235 kg), the SR/S features optimized Showa suspension and Bosch Advanced MSC for cornering stability. Braking mirrors the SR/F with advanced ABS.

Cypher III+ offers the same connectivity, plus ergonomic enhancements like an upright position and heated grips for comfort. Starting at $20,995 MSRP, it provides premium value for tourers.
