Technical Overview
2023 Bmw R 1250 R Roadster Technical Analysis & Specification Breakdown
Positioned in Bmw's naked motorcycle lineup, the 2023 Bmw R 1250 R Roadster relies on a 1254 cc (76.5 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 136 HP (99.3 kW) at 7,750 rpm while maximum torque reaches 143 Nm (105.5 lb-ft) at 6,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 108.5 HP per liter and a 1,500 rpm working window between peak torque (6,250 rpm) and peak power (7,750 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 R 1250 R Roadster measures 239 kg (527 lbs) wet (curb), translating to a power-to-weight ratio of 0.57 HP/kg (1.76 kg per horsepower). Rider ergonomics and chassis geometry center around a 818 mm (32.2 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,515 mm (59.6 in) wheelbase engineered for balanced agility and highway composure. The 18.17-liter (4.8 US gal) fuel tank paired with a rated consumption of 4.7 L/100 km provides an estimated theoretical range of roughly 387 km (240 miles) between fill-ups, while factory top speed is listed at 201 km/h (125 mph).
