R 1200 CL
Cruise Control
The R 1200 CL uses a new cable control
box to converge the operation of the throt-
tle from either the opener/closer cables of
the throttle grip or the control cable from
the cruise control actuator.
The box is located behind the fairing and
headlight assembly both of which require
removal to access. The box interconnects
four cables with two pulleys. It also con-
tains a microswitch that signals the cruise
control module when the throttle is turned
in the close direction to cancel cruise func-
tion
The spring tensioned pulleys rotate on a
shared axis. The lower pulley is attached to
the opener cable, the closer cable and the
throttle cable. The upper pulley is connect-
ed to the cruise control cable.
The pulleys rotate freely from one another
when the throttle is operated from the grip.
In this function, the twist grip pulls the
opener cable which simultaneously pulls
the throttle cable at the lower pulley.
When the cruise control actuator pulls the
cruise cable, the upper pulley rotates. A pin
on the upper pulley engages the lower pul-
ley and simultaneously operates the throt-
tle.
The pin on the upper pulley and the slot on
the lower pulley are keyed to allow full grip
control to over ride the cruise control func-
tion. When the twist grip is turned in the
opposite direction the closer cable is ten-
sioned which activates the closer switch,
signalling the cruise control to deactivate if
currently active.
There are four adjustment points on the
cables to adjust cable play. They are at the
twist grip and at the cable unions under the
fairing just forward of the spring damper.
