Function
The throttle grip is the part to which the throttle
control cables arrive; its task is to translate the rid-
er's power request (Demand) into an electrical
signal to be sent to the electronic control unit.
Operation / operating principle
The two throttle cables (opening and closing) ac-
tuate on a scroll mounted on a shaft and which is
sent back to its home position by a return spring.
On the shaft covers there are 2 double track po-
tentiometers (4 control tracks) by means of which
the torque demand is read (and checked). The 4
potentiometers are tinned and magnetically con-
trolled (contactless); they cannot be overhauled
nor replaced
