The BMW R1250GS is a motorcycle manufactured in Berlin, Germany by BMW Motorrad, part of the BMW group. It is one of the BMW GS family of dual sport motorcycles. It has a 1,254 cc (76.5 cu in), two-cylinder boxer engine with four valves per cylinder and variable valve timing (VVT).

History

[edit]

In September 2018, Kevin Cameron wrote that a "shift cam" VVT system was destined for a 2019 model year R1250GS, and other media reported the technology was to be adopted on all the R series boxer motors.[1][2] In September 2018, BMW confirmed the 2019 R1250GS and sibling R1250RT would have VVT.[3]

Chassis

[edit]

Wet weight is up from the predecessor to 249 kg (549 lb).[4]

Engine

[edit]

The engine displaces 1,254 cc (76.5 cu in) with 102.5 mm (4.04 inches) mm bore × 76 mm (3.0 inches) stroke. The intake camshafts have two cam lobes per valve that can be switched within one cam revolution between partial-throttle and open-throttle cam profiles.[1][5] Power and torque claimed by BMW are higher than the predecessor model at 134 hp (100 kW) at 7,750 rpm and 105.5 lb⋅ft (143.0 N⋅m) at 6,250 rpm, with 4% better fuel economy.[5]
