Qss - Yamaha Tracer 9 Owner's Manual

QSS

The quick shift system allows for clutch
lever-less, electronically-assisted shift-
ing. When the sensor on the shift rod
detects the appropriate motion in the
shift pedal, engine power output is mo-
mentarily adjusted to allow for the gear
change to occur.
QSS does not operate when the clutch
lever is pulled, therefore normal shifting
can be done even when QSS is set to
on. Check the QS indicator for current
status and usability information.

Indicator
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
can be individ-
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
to regulate applied brake power when
cornering to suppress lateral wheel
slip.
