LAUNCH CONTROL SYSTEM
When the launch control system is operated, the
ignition timing is delayed to reduce slipping at
the rear wheel which occurs when the vehicle
accelerates from a stationary position.
This can be used to starting off in a stable man-
ner on a slippery road surface.
However, the effect may not be adequate de-
pending on the rider’s operations and road sur-
face conditions.
How to operate
1. Put the gear into the neutral position.
2. Start the engine.
3. Push the mode switch “1” for more than one
second to turn on the launch control system.
TIP
• When the launch control system is turned on, it
automatically enters Rev. clip mode, and then
the indicator light “2” will flash.
•
The drive mode can be changed even when
the launch control system is operating.
•
When the indicator light flashes alternately pur-
ple and blue, drive mode 2 is selected.
4. Put the gear into the 1st or 2nd gear for start-
ing off.
TIP
• When starting off, the system automatically
controls the launch.
• The drive mode can be changed even when
the launch control system is operating.

ple and blue, drive mode 2 is selected.
