nevertheless in full conformity with legal standards. And last but certainly
not least, the hexagonal shape of the muffl er allows the rider to lean over to
a low angle in bends for a sporting style of riding pleasure.
The entire muffl er system made of stainless steel weighs a mere
9.4 kilos/20.7 lb (K 1200 S: 10.4 kilos/22.9 lb) and is therefore the lightest and
most compact exhaust system with a fully controlled catalytic converter in
this segment of the market. All other manufacturers require an exhaust system
with two muffl ers.
The K 1300 S is also available with a very light and sporting slip-on muffl er
made of titanium and featuring a carbon cover as special equipment from

ASC for even greater safety when accelerating.
The K 1300 S comes as an option with ASC Anti-Spin Control fi tted at
the factory and taking the signifi cantly greater power and torque of the new
four-cylinder into account.
Particularly on a high-torque motorcycle and on road surfaces varying
frequently, ASC is a very sensible addition to ABS, preventing the rear wheel
from spinning when accelerating and thus losing lateral stability, which
otherwise might make the rear end swerve out of control.
By comparing the speed of the front and rear wheels with the help of the
ABS sensors, the electronic control unit determines when the rear wheel is
spinning, engine management taking back the ignition angle and intervening
in the fuel injection process to reduce engine power accordingly.
The particularly sporting rider also has the option to deactivate ASC
while riding and is also able to switch off ABS as long as the motorcycle
is at a standstill before setting out.
