2019 Zero S Technical Analysis & Specification Breakdown
Positioned in Zero's naked motorcycle lineup, the 2019 Zero S features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 60 HP (43.8 kW) at 5,300 rpm while maximum torque reaches 110 Nm (81.1 lb-ft), transferring power to the rear wheel through a automatic gearbox and belt final drive.
On the scales, the S measures 205 kg (452 lbs) wet (curb), translating to a power-to-weight ratio of 0.29 HP/kg (3.42 kg per horsepower). Rider ergonomics and chassis geometry center around a 807 mm (31.8 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry.
