2019 Bmw C 400 X Technical Analysis & Specification Breakdown
Engineered by Bmw for the scooter motorcycle segment, the 2019 Bmw C 400 X relies on a 350 cc (21.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 34 HP (24.8 kW) at 7,500 rpm while maximum torque reaches 35 Nm (25.8 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 97.1 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the C 400 X measures 204 kg (450 lbs) wet (curb), translating to a power-to-weight ratio of 0.17 HP/kg (6 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,565 mm (61.6 in) wheelbase engineered for planted straight-line stability. The 12.8-liter (3.4 US gal) fuel tank paired with a rated consumption of 3.5 L/100 km provides an estimated theoretical range of roughly 366 km (227 miles) between fill-ups, while factory top speed is listed at 139 km/h (86 mph).
