Brake system - with BMW Integral ABS*

Partially integral brakes
The integral brake function
interlinks the front and rear
brakes, so both wheels are
braked when you operate the
brake lever.
The electronic controller in the
BMW Integral ABS* computes
the braking-force distribution
between front and rear wheels,
and applies the brakes accord-
ingly.
The baking-force distribution
depends on load and is recal-
culated every time the ABS
controller comes into action.
In this partially integral brake
configuration, the integral brak-
ing function is activated only
when you pull the handbrake
lever. The footbrake lever acts
only on the rear brake.
Brake servo
The hydraulic pump in the BMW
Integral ABS* actively boosts
the braking force acting on the
wheel when the brakes are
applied.
By boosting the braking force in
this way, the BMW Integral
ABS* achieves a higher braking
efficiency than standard brake
systems.
ABS - anti-lock brake
system*
ABS prevents the wheels lock-
ing under heavy braking when
the motorcycle is travelling in a
straight line, thus contributing
significantly to road safety.
