The motor of the Zero FX is configured to produce more torque than any other motorcycle in the lineup. The result is thrilling acceleration. Zero Motorcycles designed the Z-Force™ motor from the ground up to be compact, efficient and powerful. Completely air cooled, the motor is designed to provide a fantastic riding experience minus the need for any regular maintenance. When slowing down, the motor generates electricity that is channeled back into the power pack to help extend ride times.

  • Produces 44 hp and 70 ft-lbs of torque
  • Requires no routine maintenance
  • Operates with such high efficiency that it does not require any complex cooling system
  • Increased torque and broad power band for much stronger acceleration
  • Quad-level regenerative system recharges the power pack when decelerating
    • Re-gen level is increased during brake application vs. “neutral” deceleration
    • Both braking and “neutral” re-gen levels are set higher in Eco vs. Sport mode
    • Eco mode re-gen levels can be customized using the Zero Motorcycles App



The Zero FX charging system is integrated into the motorcycle and can be plugged in at any standard outlet. No additional equipment is required for standard charging. This allows you to conveniently charge in your garage, at the office or when you stop at one of your favorite places while enjoying a day out. Plug the Zero FX in during the evening, or while at the office, and it is ready to go when you are. Those interested in fast charging can reduce charge times from 0-95% to as little as one hour using the CHAdeMO accessory.

The Zero FX power pack modules can be removed from the motorcycle and charged separately using an optional accessory. This makes it possible to charge the modules anywhere you take them and thereby eliminates the necessity of a street-level outlet.



At the core of the Zero FX lies the ultimate dirt bike frame that Zero has engineered from the ground up and hand crafted using aircraft grade aluminum.
