has at long last released details of its new K1200S.
The new bike is a huge departure from the norm for BMW and
it's a bike that has a number of innovative features. A new
engine for the 1200S, a transverse in-line four instead of
the longitudinal in-line fours in previous K models, BMW claims
the 1157cc engine is the narrowest in its class and produces
160bhp. The cylinders are also tilted forward 55 degrees thus
keeping the weight low down and distributing the mass of the
bike evenly from front to rear.
The new K1200S uses a new non-telescopic
electronically adjusted front suspension design with two parallel
links, which BMW says "decouples wheel control from suspension
and damping" and "transfers the forces optimally
into the frame structure" for "steering precision
second to none even when braking." The drivetrain uses
BMWs traditional shaft final drive with an all-new gearbox,
and the bike retains BMW traditions like anti-lock braking
(ABS) and a catalytic converter in the exhaust.
Here is BMW's official announcement
about the K1200S.
BMW MOTORRAD RAISES THE VEIL: The
K 1200 S high performance sports bike
time for speculation is over. Now it's official: this year
BMW Motorrad will introduce the K 1200 S, a completely new
and fascinating high performance motorcycle in the sport segment.
The K 1200 S was designed as a sport bike
and is a completely separate motorcycle within the K family.
It is radically new, featuring an unprecedented number of
innovations. It is a high-precision sport bike offering unique
agility as well as enormous output. Its power to weight ratio
is on the level with the competition and almost 50 percent
better than the K 1200 RS, thus leaving no wishes unfulfilled
with regard to riding performance.
The low weight and extremely agile chassis
help the K 1200 S deliver superior handling in any situation.
The K 1200 S is powered
by a transversely mounted 1157-cc four-cylinder inline engine
with integrated transmission and is unique among sport bikes
due to its overall concept in conjunction with the lightweight
construction shaft drive.
The extreme forward tilt of the cylinder
bank (55 deg.) ensures a low center of gravity. In this way
it was possible to achieve an ideal wheel load distribution
of 50:50 percent in combination with the overall geometric
layout. The engine has an extraordinarily narrow design achieved
by a series of special design features. The engine width at
the crankshaft level is approximately the same as for 600-cc
engines. This not only allows for very deep engine installation
and maximum lean angle, it also gives the bike a narrow and
The engine can rev up into the five-digit
regions and output exceeds 160 hp (more than 117 kW). Environmental
compatibility is safeguarded by a closed-loop three-way catalytic
converter and digital engine electronics, which have been
standard features on all BMW motorcycles for years. The engine
of the K 1200 S is based on the latest generation as presented
at the beginning of the year in the R 1200 GS. It also features
integrated knock control and in this advanced four-cylinder
engine, it represents the most sophisticated engine management
system currently available for motorcycles.
The K 1200 S is also highly
innovative on the suspension side. A revolutionary front wheel
suspension using two parallel links—without telescopic
forks—ensures extremely sensitive response together
with excellent precision, outstanding overall rigidity and
low weight. The electronically adjustable suspension also
represents a world first in production motorcycle manufacturing.
The new K 1200 S is of course also equipped
with the unique BMW Motorrad Integral ABS in the partially
integral version. In conjunction with the EVO brakes, this
system ensures maximum deceleration and the shortest of braking
distances in all road conditions.
The new BMW K 1200 S will be presented to
the international public in September of this year at the
INTERMOT motorshow in Munich. It will be launched onto the
market soon after. The price has not yet been set. All familiar
models of the K family, the K 1200 RS, the K 1200 GT and the
K 1200 LT will remain part of the model range beyond 2004.
