ZF14.4+ Battery Pack

The all-new ZFORCE 14.4+ lithium-ion battery makes the SR capable of a 227-mile maximum range when combined with available Cypher Store upgrades and the available Power Tank accessory (dealer-installed available in spring of 2022). 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. Key software upgrades available in the Cypher Store will unlock up to 17.3 kWh of battery capacity and the additional 3.6 kWh Power Tank* brings the total available battery capacity to nearly 21 kWh.

* Note: Zero's Power Tank will be available in the Fall of 2022.

ZF75-10 Motor

The ZF75-10 motor is tuned for the SR to deliver 122 ft-lbs of torque, 73 hp, and 104mph, but when paired with available on-demand upgrades through the Cypher Store, those numbers soar to 140 ft-lbs of torque and 110 hp, effortlessly propelling the SR 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.

Effortless Power

The unprecedented combination of industry-leading power, control, and connection.

Rapid Charge System

Our scalable Rapid Charge System allows the SR to be configured for different charging levels. The all-new SR comes with 3 kW of charging but that can be increased by 10% with the tap of a finger through purchasing on-demand upgrade in the Cypher Store. The SR also comes with the option to add a Rapid Charge Module as a dealer installed accessory that, when combined with the Cypher Store upgrade, brings total available charging capacity to 9.3 kW and will charge the SR's 14.4+ kWh battery in just over an hour.

* Note: SR requires use of included EVSE cord in order to charge on a standard 110 V wall outlet.

Power Pivot

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.
