LAUNCH CONTROL SWITCH

The launch control switch "1" is located on top of
the right handlebar.
When the launch control switch is pressed, 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.
