2021 Bmw G 310 R Technical Analysis & Specification Breakdown
Engineered by Bmw for the sport motorcycle segment, the 2021 Bmw G 310 R features a 313 cc (19.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 33.5 HP (24.5 kW) at 9,500 rpm while maximum torque reaches 28 Nm (20.7 lb-ft) at 7,500 rpm. With a specific output of 107 HP per liter and a 2,000 rpm working window between peak torque (7,500 rpm) and peak power (9,500 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 G 310 R measures 158.5 kg (349 lbs) dry, translating to a power-to-weight ratio of 0.21 HP/kg (4.73 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 3.33 L/100 km provides an estimated theoretical range of roughly 330 km (205 miles) between fill-ups, while factory top speed is listed at 143 km/h (89 mph).
