2024 Zero SR-S Technical Analysis & Specification Breakdown
Built around Zero's sport motorcycle platform, the 2024 Zero SR-S features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 110 HP (80.3 kW) at 5,000 rpm while maximum torque reaches 190 Nm (140.1 lb-ft), transferring power to the rear wheel through a 1-speed gearbox and belt final drive.
