Previous RT models, 1978 to 2005 BMW Motorrad began manufacturing RT (
Reise-Tourer, or travel tourer) touring motorcycle models in the late 1970s. The first of these were
air-cooled (or "
airhead") models that continued BMW's long tradition dating to 1923 of producing "boxer" or opposed
flat-twin engined motorcycles with
unit engine-transmission construction and shaft-final-drive. In 1995, BMW produced its first air and
oil-cooled (or "
oilhead") RT model, the
R1100RT. The new machine included standard
ABS brakes, four-valve heads, five-speed gearbox,
Telelever front suspension,
Paralever rear suspension, and an electrically adjustable screen. In 2001, BMW launched the
R1150RT, providing the same basic platform with increased engine capacity and horsepower, fully linked power-assisted ABS brakes, revised front lighting system, and a six-speed gearbox. This model was further updated in 2004 by the adoption of
dual ignition, with two
spark plugs per cylinder.

A low seat and/or a lowered suspension were available for shorter riders reducing seat height to a lowest level of , in BMW's
traction control system for motorcycles. An electronic
tire pressure monitor (TPM) was introduced as an option. During the production of the 2006 models, the original two-tone horns were replaced by a single-tone horn. Other optional equipment included
cruise control, heated grips, heated seats for both the rider and passenger and a CD/Radio audio system. With and of torque, the R1200RT is suitable for long-distance touring carrying a rider and passenger and a full load of luggage; and is able to reach and do a standing quarter mile in 12.2 seconds. There were some relatively minor styling changes and revisions to the screen and cockpit designs, switchgear (including conventional indicators), and location of the hydraulic fluid reservoirs.
2014 to 2018 The 2014 model represented a wholesale redesign of the R1200RT. The biggest change was a shift to a water cooled version of the boxer engine, producing dyno tested and torque. BMW claimed 125 horsepower and 92 lb/ft of torque with their own
testing methodology. The seat and seating position, fairing, instrumentation, and frame were also updated. The standard ride modes "Rain" and "Road" can also be activated at the press of a button to adapt to weather conditions and road surfaces. An on-board computer, an electrically operated windshield, standard color-matched saddle bags, and heated grips were also basic items. Optional equipment for the 2014 RT includes semi-active electronic suspension adjustment, and BMW Dynamic ESA, which response to changing road surfaces, and a shift assistant pro that allows the rider to shift up and down without using the clutch or throttle. A central locking system locks both cases by remote control. Other options are a radio, a top case, low or high saddles, a tank bag, cruise control, and (introduced for the 2015 model) keyless ignition and locking The 2017 R1200RTs are fitted with a judder damper on the transmission output shaft to control rapid and forceful shaking and vibration. New features also include a revised selector drum actuator, transmission shafts, and transmission shaft bearing. As part of the Ride Modes Pro option package, ABS Pro was available, which senses a lean angle and adjusts intervention accordingly. The only changes for the 2018 model year were colors.
2019 In mid-2017
Motorrad reported that BMW was planning to soon introduce
variable valve timing (VVT) on its boxer engines. In March, 2018,
Bennetts announced that BMW was testing an RT with VVT, possibly a successor to the R1200RT. In September,
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. BMW confirmed the R1250RT would have VVT in September 2018. ==Specifications (2005–2013)==
