Throttle Control

All models have an electronic throttle
twist grip to open and close the throttle
via the engine control unit. There are no
direct-acting cables in the system.
The throttle grip has a resistive feel to it
as it is rolled rearwards to open the
throttle. When the grip is released it will
return to the throttle closed position by
its internal return spring and the
throttle will close.
There are no user adjustments for the
throttle control.
