2021 Zero SR/F Electric Motorcycle

The SR/F delivers 140 ft-lbs of torque and 110 horsepower with the simple twist of a throttle thanks to the class-leading performance and efficiency of Zero’s new ZF75-10 motor and ZF14.4 lithium-ion battery.

The ZF14.4 lithium-ion battery makes the SR/F capable of a 200-mile maximum range.* The battery’s industry-leading power and energy density combined with an aluminum heat-sink housing and thermal transfer interface ensure consistent cell cooling and maximum long-term powertrain performance.

The ZF75-10 motor delivers 140 ft-lbs of torque and 110 hp, effortlessly propelling the SR/F to a top speed of 124 mph. Pairing Zero’s renowned internal permanent magnet brushless architecture and a passively air-cooled compact design creates class-leading performance and efficiency.

Our all-new scalable Rapid Charge System allows the bike to be configured for 3 kW, 6 kW, 9 kW or 12 kW of charging at any standard Level 2 charge station.* The SR/F Rapid Charge System will be able to charge at 38 miles of range per hour of charging (mphc) on 3 kW, 76 mphc on 6 kw, and 153 mphc on 12 kW which can recharge the battery pack to 95% capacity in 1 hour of charging.

A proprietary concentric motor and swingarm pivot design provide the optimal architecture to ensure constant drive-belt tension and maximum torque delivery to the rear wheel. A custom-designed, large-bearing swingarm pivot allows ample space for the high-performance motor while allowing a slim chassis waist to enhance rider ergonomics and bike maneuverability.
