TIRE TREAD CONDITION
Operating the motorcycle with excessively worn tires will
decrease riding stability and consequently invite a dangerous
situation. It is highly recommended to replace a tire when the
remaining depth of the tire tread reaches the following specifica-
tion.

TIRE PRESSURE
If the tire pressure is too high or too low, steering will be
adversely affected and tire wear will increase. Therefore, main-
tain the correct tire pressure for good roadability and a longer
tire life. Cold inflation tire pressure is as follows.

The standard tire fitted on this motorcycle is a 120/
70ZR17 M/C (58W) for the front (GSF650: BRIDGE-
STONE BT011F L, GSF650S: BRIDGESTONE BT011F
J) and a 160/60ZR17 M/C (69W) for the rear (GSF650,
GSF650S: BRIDGESTONE BT020R L). The use of tires
other than those specified may cause instability. It is
highly recommended to use the specified tires.

STEERING

Inspect initially at 1 000 km (2 month) and every 12 000
km (24 months) thereafter.
The steering should be adjusted properly for smooth turning of
the handlebars and safe operation. Overtighten steering pre-
vents smooth turning of the handlebars and too loose steering
will cause poor stability. Check that there is no play in the front
fork. Support the motorcycle so that the front wheel is off the
ground. With the wheel facing straight ahead, grasp the lower
fork tubes near the axle and pull forward. If play is found, read-
just the steering. (!5-28)
