The BMW R1250RS is a sport touring motorcycle (Reise Sport) produced by BMW Motorrad. It was unveiled at EICMA in November 2018.[2] Like the other versions of the R-series, which include the R1250RT, R1250R (Roadster) and R1250GS, the motorcycle model is powered by a boxer engine.

Specifications

Powertrain

The air- and water-cooled two-cylinder engine produces a nominal output of 100 kW (136 hp) at 7750 rpm and a maximum torque of 143 Nm at 6250 rpm from a displacement of 1254 cm³. It has a sliding camshaft (shiftcam) that adjusts the timing for the lower, middle and upper speed ranges and changes the intake valve lift.[2][3] Depending on the position, a partial load or full load cam acts on the valves. A regulated three-way catalytic converter treats the exhaust gas. The engine meets the Euro 5 emissions standard.[2] There is also engine drag torque control (MSR). Consumption in the WMTC cycle is given as 4.75 l/100 km (CO2 emissions are 110 g/km).[4] The magazine Motorrad und Reisen reports from around 3.9 to around 5.3 l/100 km.[1]

Design

The frame consists of a main frame and a rear frame bolted to it, with the engine also serving as a load-bearing element. The R1250RS has an upside-down telescopic fork at the front and a cast aluminum single-sided swingarm at the rear.[1] The chassis is complemented by traction control (Dynamic Traction Control, DTC) and Pro driving modes with driving mode preselection. On request, a semi-active chassis with automatic level control to adapt to the load condition is available.[5]

The R1250RS is equipped with two LED headlights[6] and a 6.5-inch TFT display. The eCall emergency call is available upon request, as are add-on parts milled from solid aluminum.[2] The 6-speed transmission can be equipped with shift support, also known as quickshifter or blipper.[5] The machine has an 18-liter tank (including 4 liter reserve).[4]
