Frame / Bodywork

The Zero S Electric Motorcycle utilizes aircraft-grade aluminum in its lightweight and rigid twin-spar frame, contributing to its durability and aggressive appearance. This frame is specifically designed for urban environments, offering strong and maneuverable support. The bodywork includes custom-injected molded plastics that enhance aerodynamics and supermoto styling.

  • Construction: Lightweight twin-spar frame made from aircraft-grade aluminum
  • Body: Custom-injected molded plastics with new color graphics for styling and aerodynamics
  • Design: Low center of gravity for enhanced maneuverability and responsiveness

Power Pack / Electronics

With years of development and proprietary Z-Force™ technology, the Zero S is designed for optimal acceleration, range, and longevity. The power pack features an advanced monitoring system that individually controls each cell during charging and discharge, maximizing efficiency and performance. Additional onboard systems support standard 12-volt current for accessories like lighting and the dashboard.

  • Technology: Z-Force™ power pack for improved acceleration and range
  • Safety: Redundant safety features for extreme conditions
  • Charging: Onboard charger with a specialized charge profile for quick recharging
  • Ignition: Keyed ignition linked to a solenoid switch for secure power-up

Motor / Z-Force Air Induction

The compact and powerful motor is complemented by the Z-Force Air Induction system, which allows for efficient air movement through the core to boost motor performance. This motor is mounted low in the frame, supporting high torque and increased acceleration while maintaining a low center of gravity.

  • System: Z-Force Air Induction for enhanced motor performance
  • Design: Lightweight, compact motor with high efficiency and low maintenance
  • Positioning: Low frame mount for better maneuverability

Wheels and Brakes

The Zero S wheels are engineered to reduce unsprung weight and rotating mass, featuring a high-performance wheel set with a lightweight design. Custom hubs, spokes, and rotors work in unison for a stronger and more responsive wheel construction.

  • Wheel Set: High-performance with custom hubs and straight-pull spokes
  • Tires: Aggressive profile street tires
  • Brakes: Full-float calipers with foot-actuated rear and hand-actuated front brakes

Suspension

Zero designed the Zero S suspension to align with its lightweight build, using an inverted front fork to minimize unsprung weight. The front suspension allows for external adjustment of compression and rebound damping, while the rear features a unique double diamond swingarm and an adjustable custom shock.

  • Front Fork: Inverted design for reduced weight and adjustable damping
  • Rear Shock: Adjustable spring preload and damping
  • Swingarm: Double diamond aircraft-grade aluminum for reduced weight and increased rigidity

Dash / Lights

The dashboard provides real-time information on speed, charge level, and motor temperature. With evening visibility in mind, the dash lights up with the flip of a switch, accompanied by a high-intensity headlight for night riding.

  • Display: Digital and analog speed readout
  • Sensors: Motor temperature monitoring
  • Lighting: High-intensity headlight for night visibility

Gearing

The Zero S features a clutchless, single-speed gearing system designed for rapid acceleration and minimal frictional loss. Direct chain drive and hardened alloy sprockets help maximize efficiency and increase the motorcycle’s range.

  • Transmission: Clutchless one-speed
  • Design: Direct chain drive for reduced friction
  • Maintenance: Minimal requirements for enhanced efficiency
