Traction Control System - Yamaha YZF-R1 Owner's Manual

Traction control system

The traction control system helps main-
tain traction when accelerating. If sen-
sors detect that the rear wheel is
starting to slip (uncontrolled spinning),
the traction control system assists by
regulating engine power as needed un-
til traction is restored. The traction con-
trol system indicator/warning
flashes to let the rider know that traction
control has engaged.
WARNING
The traction control system is not a
substitute for riding appropriately
for the conditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
turns, when accelerating hard at a
sharp lean angle, or while braking,
and cannot prevent front wheel slip-
ping. As with any motorcycle, ap-
proach surfaces that
slippery with caution and avoid es-
pecially slippery surfaces.
