A throttle sensor mounting structure by which a throttle sensor can be mounted
so that shock resistance thereof is enhanced and detection errors are reduced.
Fork portions of a front fork are connected to each other at upper end portions
thereof through a top bridge and on the lower side thereof through a bottom bridge.
The opening of a throttle grip, i.e., the throttle opening is transmitted to a
throttle sensor as a displacement of a throttle cable. The throttle sensor has
its base member screwed to bosses provided at two positions on the front side of
the top bridge by screws whereby it is so fixed that its major portion including
a sensor portion is disposed between the top bridge and the bottom bridge.
