Conception
The K 1200 R is technically the BMW K 1200 S is very similar, but without the full fairing, with a higher handlebar, modified power delivery, revised steering angle and trail. The bike accelerates in 2.9 seconds from 0 to 100 km / h and was up to the presentation of the Suzuki B-King in 2007, the most powerful series-produced muscle bike in the world.
Construction
Drive
The liquid-cooled four-cylinder engine produced from 1157 cc capacity is rated at 120 kW (163 hp) and a maximum torque of 127 Nm at a speed of 8250 min -1. The cylinder head of the transversely-mounted in-line engine has two overhead camshafts, which control by rocker arms per cylinder, two intake and two exhaust valves. The four cylinders of the four -stroke engine has a bore of 79 mm diameter, the pistons have a stroke of 59 mm and a compression ratio of 13:1. The top speed is 262 km / h
Power transmission
The primary mechanism via a helical gears. The force of separation is made possible by a hydraulically actuated multi-plate clutch in oil bath, the torque conversion by a Constant mesh six speed gearbox. The secondary drive is a shaft drive.
Fuel supply
A digital control system controls the electronic fuel injection with integrated knock control (BMS -K). The average fuel consumption is 5.5 liters per 100 km at a speed of 120 km / h The fuel tank is made of plastic and has a volume of 19 liters, including 4 liter reserve. The manufacturer recommends the use of motor gasoline with an antiknock properties of at least 98 octane. The exhaust after-treatment is carried out by a fully controlled three -way catalytic converter and below the limit values for pollutants emission standard Euro - third
Landing gear
The chassis is based on a bridge frame made of aluminum and has a load-bearing engine-gearbox unit. The front wheel is run by a Duolever with central spring strut and 110 mm spring travel. The rear wheel is performed by a cast aluminum swingarm with Paralever. On the front tire a delayed double disc brake with 320 mm in diameter and the rear disc brake with a 265 mm. A turn-off anti -lock braking system was offered as an option. The wheels made of cast aluminum front have the dimensions 120/70 ZR 17 and rear 180/55 ZR 17
Compared to the fully faired BMW K 1200 S, the R has a wider handlebars and a shorter fuel tank, whereby the driver sits further forward and upright. In combination with the shortened by 11 mm of the front wheel tracking results in a slightly higher agility.

Reviews
"Here is a naked, pure motorcycle. The technique is visible from all sides, for the driver, there is little protection from the advancing rush of air masses - but is precisely what makes the charm of the so-called naked bikes or Roadster motorcycles from ".
" There are also low center of gravity through the inclined mounting position of the engine and the driving dynamics peculiarity of Duolever front suspension, hardly einzufedern during deceleration. In interaction with the powerful series of four, this means: On a K 1200 R one is extremely fast, but also extremely unspectacular way. Since increases even under full power operation no front wheel if you do not vigorously pulling on the handlebars. And with no rear hearty braking maneuvers. Always keep the wheels where they belong, and they run under all circumstances in the track, because significantly distort the fork or any of the short frame. "
" But so gorgeous, the wonderful high-torque motor evil and behaving with the desired by BMW employees mentioned image of almost drivable monster 's then nothing. The track makes the stable, predictable and well - what a nasty word - good-natured chassis a big spanner in the works ".
