It is one of the BMW GS family of dual sport motorcycles. It has a {{cvt|1254|cc}}, two-cylinder boxer engine with 4-valves per cylinder and variable valve timing (VVT). HistoryIn 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] ChassisWet weight is up from the predecessor to {{convert|249|kg}}.[4]EngineThe engine displaces {{cvt|1254|cc}} with 102.5 mm bore × 76 mm stroke. There are 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 {{convert|134|hp}} at 7750 rpm and {{convert|105.5|lb·ft}} at 6250 rpm, with 4% better fuel economy.[5] References1. ^1 {{citation|author=Kevin Cameron|first=|title=BMW Adopts Variable Valve Timing On 2019 R1250GS Adventure Bike|date=September 14, 2018|url=https://www.cycleworld.com/bmw-adopts-variable-valve-timing-on-2019-r1250gs-adventure-bike|work=Cycle World|volume=|pages=}} 2. ^{{citation|title=Here Is the BMW R1250GS with "Shiftcam" Engine Technology|author=Jensen Beeler|date=September 13, 2018|work=Asphalt & Rubber|url=https://www.asphaltandrubber.com/bikes/2019-bmw-r1250gs-shiftcam-variable-valves-vvt/}} 3. ^{{citation|publisher=Motorcycle.com|title=2019 BMW R1250GS And R1250RT With ShiftCam VVT Announced|date=September 17, 2018|author=Dennis Chung|url=https://www.motorcycle.com/mini-features/2019-bmw-r1250gs-r1250rt-shiftcam-vvt-announced.html}} 4. ^{{citation|work=Motor Cycle News|title=BMW release full details of 2019 R1250GS|date=September 17, 2018|url=https://www.motorcyclenews.com/news/new-bikes/2019-bmw-r1250gs/}} 5. ^1 {{citation|title=2019 BMW R1250GS And R1250RT With ShiftCam VVT Announced|publisher=Motorcycle.com|date=September 17, 2018|url=http://www.motorcycle.com/mini-features/2019-bmw-r1250gs-r1250rt-shiftcam-vvt-announced.html}} External links{{Commons category|BMW R1250}}
