Technical Overview
2021 Bmw Definition CE 04 Technical Analysis & Specification Breakdown
Positioned in Bmw's prototype - concept model motorcycle lineup, the 2021 Bmw Definition CE 04 features a purpose-built liquid-cooled electric configuration. In factory specification, peak output is rated at 42 HP (30.7 kW) at 4,900 rpm while maximum torque reaches 61 Nm (45 lb-ft) at 4,900 rpm, transferring power to the rear wheel through a 1-speed gearbox and belt final drive.
On the scales, the Definition CE 04 measures 230 kg (507 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.48 kg per horsepower). Rider ergonomics and chassis geometry center around a 855 mm (33.7 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,675 mm (65.9 in) wheelbase engineered for planted straight-line stability.
