Features

Frame / Bodywork:
Aircraft grade aluminum is exclusively used in the construction of the lightweight and rigid Zero S twin spar frame. One look at the frame and it speaks for itself. It is aggressive, strong and one of the main reasons that the Zero S can take on anything in an urban environment. Designed to have a low center of gravity, the Zero S is highly maneuverable and responsive. The body is completed using custom injected molded plastics to give it aerodynamics and aggressive supermoto styling.

Power Pack / Electronics:
Years of development and proprietary Z-Force™ technology make the Zero S a leader in acceleration, range and longevity. Using an advanced monitoring system, each cell in the power pack is individually controlled during charge and discharge. The onboard charger integrates into this system and uses a specially developed charge profile to optimize the power pack's recharge time. Using isolated power systems the Zero S uses a standard 12 volt current to run the dash, lighting and other on board accessories.
Proprietary Z-Force™ power pack for increased acceleration and range
Redundant safety features to accommodate extreme conditions
Isolated power systems and 12 volt system for running accessories
Onboard charger that uses a specially developed charge profile
Keyed ignition tied to a solenoid switch for a safe and instant power up

Wheels and Brakes:
The Zero S wheels are engineered to minimize unsprung weight and reduce rotating mass. Designed specifically for the Zero S, the lightweight construction includes custom hubs, spokes, and rotors. To maximize overall wheel strength the hub is configured to use straight pull spokes. The resulting wheel is lighter, stronger and more responsive.
Specially developed high performance wheel set
Aggressive profile street tires
Custom designed hubs for reduced weight and maximum wheel strength
High strength/lightweight strait pull spokes
'Shark tooth' brake rotors for increased heat dissipation
Full float calipers - 4 pot front, 2 pot rear
Custom foot actuated rear and hand actuated front brake

Suspension:
The suspension on the Zero S was developed by Zero to take advantage of the motorcycles' lightweight design. Its inverted front fork is among the lightest in the industry and can be externally adjusted to dial in compression and rebound damping. A rigid double diamond rear swing arm keeps the wheel planted using a Fox rear shock with a fully adjustable spring preload and easily tuned damping.

Unique double diamond aircraft grade aluminum rear swingarm for reduced weight and increased torsional rigidity

Dash / Lights:
The dash is designed by Zero to quickly and accurately provide information on speed, charge and motor temperature. In the evening the dash lights up with the flip of a switch and is accompanied by a unique aggressively styled 'projector beam' headlight that emits focused light for increased visibility.

Gearing
A clutchless one speed, the Zero S is geared for rapid acceleration and increased efficiency. Using a direct chain drive and hardened alloy sprockets the Zero S is able to achieve minimal frictional loss. This increases the overall range and channels power into speed.
