2021 Honda CB1000R Black Edition Technical Analysis & Specification Breakdown
Engineered by Honda for the naked motorcycle segment, the 2021 Honda CB1000R Black Edition utilizes a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 143.5 HP (104.7 kW) at 10,500 rpm while maximum torque reaches 104 Nm (76.7 lb-ft) at 8,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 143.8 HP per liter and a 2,250 rpm working window between peak torque (8,250 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the CB1000R Black Edition measures 214 kg (472 lbs) wet (curb), translating to a power-to-weight ratio of 0.67 HP/kg (1.49 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,455 mm (57.3 in) wheelbase engineered for balanced agility and highway composure. The 16.2-liter (4.3 US gal) fuel tank paired with a rated consumption of 5.8 L/100 km provides an estimated theoretical range of roughly 279 km (173 miles) between fill-ups.
