EAU40472
YCC-S system
This vehicle features the YCC-S
(Yamaha Chip Controlled-Shift) sys-
tem.
The basic function of this system allows
the rider to shift gears without the use of
a clutch lever. Furthermore, a shift lever
is equipped on the handlebar, allowing
the rider to choose to shift gears either
with the shift pedal or by hand.
When the engine is started and the shift
pedal or the shift lever is moved, a sig-
nal is sent to the MCU (Motor Control
Unit) which disengages the clutch, then
the shift is made. The MCU engages
the clutch once the engine is running at
the proper speed. Clutch engagement
is controlled optimally by the MCU ac-
cording to engine r/min, engine require-
ments, and riding conditions. See
“Handlebar switches” (page 3-10) and
OPERATION AND IMPORTANT
RIDING POINTS (page 5-1) for further
explanation of this system.
NOTE:
This is not an automatic transmission,
only the clutch system is automatic.
The gears must be shifted by the rider.
