2011 BMW G 450 X Technical Analysis & Specification Breakdown

Positioned in BMW's enduro - offroad motorcycle lineup, the 2011 BMW G 450 X relies on a 449.5 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 40.2 HP (29.4 kW) at 7,000 rpm while maximum torque reaches 42.8 Nm (31.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 89.4 HP per liter and a 500 rpm working window between peak torque (6,500 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the G 450 X measures 111 kg (245 lbs) dry, translating to a power-to-weight ratio of 0.36 HP/kg (2.76 kg per horsepower). Rider ergonomics and chassis geometry center around a 955 mm (37.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,475 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 8-liter (2.1 US gal) fuel tank paired with a rated consumption of 4.5 L/100 km provides an estimated theoretical range of roughly 178 km (111 miles) between fill-ups, while factory top speed is listed at 145 km/h (90 mph).
