BMW Unleashes The Beast: K1200R

Our full feature on the new Bavarian powerhouse can be found in the BIKES section, or right here!


Just when you thought the growing "naked bike" segment - sportbikes shorn of their plastic wrappers, unveiled for all to see - was all about showing off and nothing about substance and style, here comes the 2006 BMW K 1200 R. Unlike the weightlifter who can barely scratch his own back, the K 1200 R is powerfully built yet agile, massively quick yet perfectly docile for those times you want to take it easy. It's the ideal combination of menace and class.

BMW has taken advantage of the incredible technology housed in the new K 1200 S - a straight-line speed machine that also accelerates, turns and stops like a truly modern superbike - to create the K 1200 R. In fact, except for revised bodywork and ergonomics, the two bikes are very much alike.

And yet the two motorcycles couldn't be further in temperament. The K 1200 S is sophisticated, urbane, while the K 1200 R is built for the rider who lives for sport riding and uncompromised appearances. The K 1200 R eschews full bodywork for a tidy, aerodynamically designed instrument-panel fairing that incorporates powerful asymmetrical headlights and the engine oil cooler. This is a face that performance-oriented riders won't soon forget. Nor will race fans, as the K 1200 R will form the basis for the BMW Power Cup, with races to be held all over the world on special race-prepared machines. Taking up where the popular Boxer Cup left off, it's likely that the best, hardest-fought racing in 2005 will come from the ranks of the Power Cup.

Behold the most powerful production motorcycle engine BMW has ever built, the beneficiary of decades competing at the highest levels of motorsport. But it's not just about sheer thrust. Indeed, the K 1200 R's revolutionary inline-four-cylinder engine sets new standards not just for power - and, as important, excellent power delivery - but it was designed from the start to be compact and light. Moreover, its unusual configuration - the cylinder block is canted toward the front wheel by 55 degrees - not only reduces the entire motorcycle's center of gravity but also permits innovating packaging solutions. The K 1200 R's layout is as far from a me-too arrangement as you can get.

Thorough development of the 1157cc, liquid-cooled engine made possible the 167-horsepower peak but is also responsible for the engine's broad, flat torque curve; although it peaks at 94 pound-feet, 80 percent of the peak torque is available from 3500 rpm all the way to the 11,000-rpm redline. That's flexibility.

Maintaining high power and low emissions is one responsibility of the K 1200 R's BMS-K (BMW Engine Management with Anti-Knock Control) Digital Motor Electronics. This system features fully sequential cylinder-specific fuel injection with integrated anti-knock control and a three-way catalytic converter in the exhaust. Combining the use of a sensitive oxygen sensor and fast feedback processing in the engine-control computer with special anti-knock sensors, allowed BMW's engineers to tune the K 1200 R's engine for maximum power yet retain the ability to use less-than-premium fuel. (Maximum power will be obtained on premium fuel, however.)

This sophisticated injection system allowed BMW's engineers to boost the K 1200 R's compression ratio to a race-like 13.0:1, which benefits not only power, but combustion efficiency as well. That gives the rider more power and torque, and increases fuel economy at the same time.
