LIF
The lift control system reduces the rate
at which the front wheel will continue to
rise during extreme acceleration, such
as during starts or out-of-corner exits.
When front-wheel lift is detected, en-
gine power is regulated to slow front-
wheel lift while still providing good ac-
celeration.
BC
The brake control system regulates hy-
draulic brake pressure for the front and
rear wheels when the brakes are ap-
plied and wheel lock is detected. This
system has two settings.
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
can be individ-
to regulate applied brake power when
cornering to suppress lateral wheel
slip.
BC1/BC2
WARNING
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.
