The BMW R 1200 RT MSUI is a fully faired motorcycle from the vehicle manufacturer BMW . The Tourer was presented on November 10, 2013 at the EICMA motorcycle fair in Milan and has been on the market since February 2014 as the successor to the BMW R 1200 RT (K26) . Like all models in the R series, the motorcycle is powered by a boxer engine and manufactured at the BMW plant in Berlin in Spandau . The suffix RT stands for travel tourer, the factory code is K52 .
After the R 100 RT (1978–1984), R 100 RT Classic (1987–1996), R 1100 RT (1995–2001), R 1150 RT (2001–2004) and R 1200 RT (2005–2013) is the K52 already the sixth generation of the RT series, which has been produced since 1978. In October 2018, the optically almost identical successor R 1250 RT appeared.
development
Compared to the previous model of the same name, the K52 has been completely redeveloped under the direction of the project manager Raimund Brandl. The cockpit, lighting and windshield kinematics assemblies come from the tourer BMW K 1600 GT . The air and liquid-cooled two-cylinder engine was taken over from the BMW R 1200 GS K50 travel enduro , but the crankshaft (7004 instead of 6189 grams) and the alternator rotor were given larger flywheels for smoother running. As is typical for Tourers, the speed level was lowered by a longer secondary transmission. The RT chassis is also based on the GS tubular steel frame.
construction
drive
The air- and water-cooled two-cylinder engine produced from 1170 cc a nominal power of 92 kW (125 hp) and a maximum torque of 125 Nm at a speed of 6500 min -1 . The two opposing cylinders of the boxer engine have a bore of 101 mm in diameter, the pistons have a stroke of 73.6 mm with a compression ratio of 12.5: 1. In each of the two cylinder heads of the four-stroke engine , two gear-driven, overhead camshafts (DOHC) rotate , which control two intake and two exhaust valves via rocker arms. The claw-shift gearbox has six gears with helical teeth and can optionally be operated with an automatic gearshift even without actuating the wet clutch.
The motorcycle accelerates from 0 to 100 km / h in 3.8 seconds and reaches a top speed of 225 km / h.
landing gear
The chassis consists of a front and rear frame with a load-bearing motor- gearbox unit. The steering head angle is 63.6 degrees, the caster 116 mm. The suspension setting can be changed electronically in nine stages via the spring preload and damping. The semi-integral three-disc brake system decelerates the motorcycle with an average of 9.8 m / s² in 39.5 meters from 100 km / h to a standstill. The standard, semi-integral anti-lock braking system regulates the braking behavior in critical situations. The front wheel is suspended from the fork ( Telelever ) with a triangular link and a sliding joint , the rear wheel is suspended from a single-sided swing arm (together with a link to absorb the reaction forces of the integrated cardan drive: " Paralever "). The front tires are 120/70 ZR 17 and rear 180/55 ZR 17. The turning circle has a diameter of 5.3 meters. Ready to drive and with a full tank, the Tourer weighs 274 kg. The maximum payload is 213 kg. The two side cases have a storage volume of 37 liters each.
Fuel system
The fuel tank has a capacity of 25 liters, of which approx. 4 liters are in reserve. The magazine Motorrad determined an average fuel consumption of 4.9 liters per 100 km, which results in a theoretical range on country roads of just over 500 km. The manufacturer recommends premium gasoline with at least 95 octane to refuel. A regulated three-way catalytic converter treats the exhaust gas . This means that the motorcycle falls below the emission limit values of the Euro-3 emissions standard . The engine has been compliant with the Euro-4 emissions standard since 2017.
Reviews
Thomas Schmieder criticizes in the trade journal Motorrad the “shift when shifting into first gear”, the “minimal wobbling movements ” caused by the steering damper when “creeping” and the not “excessively responsive” strut on the rear suspension.
"Numerous electronic helpers and high-quality equipment features such as the 5.7-inch TFT color display or the standard audio system further enhance the new RT without shaking the traditional concept: There is hardly a tourer that has its crew so comfortably, confidently and takes agile from A to B at the same time. "
“The K 1600 and RT have something in common. They don't drive as they look, namely more light-footed, more agile than you might think - the RT even more so than the 1600s. At 274 kilos, the travel boxer is quite light for this motorcycle category, with the new chassis, according to our first impression, even more manageable than its predecessor and at the same time stable. "
“The low center of gravity provided by the flat-twin engine allows the RT to feel much lighter and less intimidating than other 587-pound bikes might. The seat is not significantly lower than the GT's, but the RT is narrower between the rider's legs; and that, along with the light feel, gives shorter, smaller riders added confidence, especially when stopped. [...] All of this combines to make the R1200RT an extremely competent, thoroughly enjoyable motorcycle. Among the rest of the offerings in the wide and ever-expanding realm of sport-tourers, it ranks right up there with the best of them. But it gets the job done in its own inimitable way, using composure and subtlety to sneak up on excellence rather than sheer size and banshee-wail rpm to stampede it. "
“Thanks to the low center of gravity resulting from the horizontal boxer engine, the RT feels much lighter and less intimidating than comparable 276 kg motorcycles. The seat is not significantly lower than on the GT, but the RT is narrower between the driver's legs; and this, together with the feeling of lightness, gives smaller and narrower drivers additional confidence, especially when stopping. [...] All of this together makes the R1200RT an extremely competent, unreservedly pleasant motorcycle. Between the remaining offers in the wide and steadily growing market segment of sports tourers, it ranks among the best of them. But it does its job in its own inimitable way, relies on serenity and finesse instead of sheer size and screeching speeds in order to approach top performance. "
