amount of rear wheel braking force to
be applied by the UBS is based on ve-
hicle attitude and lean angle. However,
operating only the brake pedal will not
generate any brake pressure at the
front brake.
For full braking performance, apply
both the brake lever and brake pedal si-
multaneously.
When both the brake lever and the
brake pedal are applied simultaneous-
ly, the UBS will control the distribution
of braking force between the two
wheels.
TIP
 The UBS does not function until
the vehicle starts moving.
 After coming to a stop while apply-
ing the brake lever, the UBS is still
enabled. As further squeezing of
the brake lever will not increase
the braking power of the rear
brake, apply the rear brake should
further braking power be neces-
sary (such as when parking on a
slope).
The UBS disables after the brake
lever is released.
When the vehicle starts moving,
the UBS is re-enabled.
