2016 Zero SR Technical Analysis & Specification Breakdown
Engineered by Zero for the sport motorcycle segment, the 2016 Zero SR features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 67 HP (48.9 kW) at 4,000 rpm while maximum torque reaches 144 Nm (106.2 lb-ft), transferring power to the rear wheel through belt final drive.
