History

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

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

Engine

The engine displaces 1,254 cc (76.5 cu in) with 102.5 mm bore × 76 mm stroke. The intake camshaftes 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 horsepower (100 kW) at 7750 rpm and 105.5 pound force-feet (143.0 N⋅m) at 6250 rpm, with 4% better fuel economy.[5]
