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.
POTENT ACCELERATION FROM A STATE-OF-THE-ART
POWERPLANT
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.
A NEW KIND OF BALANCING ACT
Inline-four-cylinder engines have characteristic
vibration but the K 1200 R powerplant uses a technology also explored in the
new R 1200 Boxer engines to make it inherently smooth. Twin balance shafts
are driven by a toothed belt from the crankshaft at twice the crankshaft
speed and employ elastomer isolators to reduce transmission of noise and
vibration. These balance shafts reduce transmission of second-order
vibration from the engine to the chassis and, therefore, to the rider, who
will experience four-cylinder serenity as never before.
Dramatic advances in driveline technology abound in the K 1200 R. The
cassette-style six-speed transmission uses stacked shafts to reduce the
engine's overall length and to form the most efficient method of
transferring power to the shaft final drive.
CHASSIS OVERVIEW: HIGH-TECH ALLOY FRAME AND
UTTERLY UNCOMMON SUSPENSION
The K 1200 R shares the K 1200 S's chassis components,
including light-alloy main frame featuring dramatically tilted main spars -
to further reduce the machine's center of gravity - made up of a selection
of materials: pressure-cast aluminum, alloy extrusions and special die-cast
aluminum members. Because the counterbalanced engine does not vibrate like a
typical four-cylinder, it can be mounted solidly to the frame - no rubber
isolators are necessary. In this way, the frame is further strengthened by
the engine structure.
BMW has always pushed forward on suspension design,
and the K 1200 R continues the tradition. Joining a revised, lightened
version of the company's famed Paralever rear suspension - much lighter than
conventional shaft systems and without a typical shaft's squatting
tendencies - is the Duolever front suspension. Based on a concept developed
by British inventor Norman Hossack in the 1980s, Duolever effectively
isolates suspension movement from steering forces for smooth handling.
Moreover, Duolever has significantly less friction than conventional
telescopic forks, so its action is much more supple while also being given
spring and damping rates appropriate for a sportbike. Finally, the Duolever
has been designed to provide effective anti-dive control so that the K 1200
R remains on an even keel during hard braking.
And it's not just the suspension design that breaks
new ground, either. As with the K 1200 S, the K 1200 R features BMW's ESA -
Electronic Suspension Adjustment - as an option. Accessed through the
instrument panel display, ESA sets spring and damping rates electronically.
The rider can choose three combined spring settings - solo, solo with
luggage or rider with passenger and luggage - along with three damping
modes: comfort, normal or sport. The spring settings must be adjusted at a
standstill, but the damping adjustments can be made while underway.
IMPRESSIVE BRAKES AND ADAPTIVE ANTI-LOCK CONTROL,
TOO
BMW's acclaimed EVO brake system is standard on the K
1200 S. Integral ABS is available as an option. Disc diameters in front are
320mm with a single 265mm disc at the rear. The K 1200 S includes BMW's
Partial-Integral adaptive braking system. Both brakes -- front and rear --
are activated whenever the rider pulls the handlebar-mounted lever, but only
the rear brake is activated by the foot pedal. BMW has continued to develop
the EVO ABS system and for the K 1200 S, the technology has been refined
once again to take full advantage of the bike's peerless sporting
performance.
These powerful brakes work through new-design wheels
that are light yet strong. They carry traditional sportbike-sized tires - a
120/70ZR17 in front and a large-footprint 180/55ZR17 at the rear.
