Brake control system (BC)
The brake control system regulates hy-
draulic brake pressure for the front and
rear wheels independently when the
brakes are applied and wheel lock is
detected. This system has two settings
which can be changed in the settings
MENU. (See page 5-16.)
BC1 is standard ABS, which adjusts
brake pressure based on vehicle speed
and wheel speed data. BC1 is de-
signed to engage and maximize brak-
ing when the vehicle is upright. BC2
uses additional data from the IMU to
regulate applied brake power when
cornering to suppress lateral wheel slip.
Regarding ABS, operate the brakes as
you would conventional brakes. When
the brake control system engages, a
pulsating sensation may be felt at the
brake lever or brake pedal as the hy-
draulic unit rapidly applies and reduces
brake pressure. In this situation, contin-
ue to apply the brake lever and brake
pedal to allow the ABS to work—do not
“pump the brakes” as this will reduce
braking effectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer with
the ABS than without.
The ABS hydraulic unit is monitored by
the ABS ECU, which will revert the sys-
tem to conventional braking if a mal-
function occurs.
WARNING
EWA20891
The brake control system is not a
substitute for the use of proper rid-
ing and braking techniques. The
brake control system cannot pre-
vent all loss of traction due to
over-braking from excessive speed,
or lateral wheel slip when braking on
slippery surfaces.
TIP
The ABS performs a self-diagnostic
test when the vehicle is started and
reaches a speed of 5 km/h (3 mi/h).
During this test, a clicking noise may be
audible from the hydraulic control unit,
and a vibration may be felt at the brake
lever or pedal, but this is normal.
NOTICE
ECA20100
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.
