ESSENTIAL INDIVIDUAL COMPONENTS
To change to a slower speed: Push and hold the SET/DECEL
switch and the motorcycle will slow down; when you reach the
desired slower speed, release the switch and the system will be
reprogrammed. For temporary acceleration above the set
speed, such as for passing, use the throttle conventionally.
When you want to return to the set speed, close the throttle
and coast without applying the brakes.
NOTE:
• With the Cruise Control on, your speed will still vary
slightly, particularly going up or down hills.
