Technical Overview
2021 Zero DSR BF Technical Analysis & Specification Breakdown
Positioned in Zero's super motard motorcycle lineup, the 2021 Zero DSR BF features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 70 HP (51.1 kW) at 3,500 rpm while maximum torque reaches 157.3 Nm (116 lb-ft), transferring power to the rear wheel through a automatic gearbox and belt final drive.
On the scales, the DSR BF measures 222 kg (489 lbs) wet (curb), translating to a power-to-weight ratio of 0.32 HP/kg (3.17 kg per horsepower). Rider ergonomics and chassis geometry center around a 843 mm (33.2 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,427 mm (56.2 in) wheelbase engineered for balanced agility and highway composure.
