Steering System Inspection
Inspect steering system
Initially at 1 000 km (600 miles, 2 months) and every
12 000 km (7 500 miles, 24 months) thereafter.
Steering should be adjusted properly for smooth turning
of handlebars and safe running. Overtighten steering
prevents smooth turning of the handlebars and too loose
steering will cause poor stability.
1) Check that there is no play in the front fork.
2) 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, readjust the steering. Refer to
"Steering Tension Adjustment in Section 6B
(Page 6B-10)".
Front Fork Inspection
Inspect front fork
Every 12 000 km (7 500 miles, 24 months)
Inspect the front forks for oil leakage, scoring or
scratches on the outer surface of the inner tubes.
Replace any defective parts, if necessary. Refer to
"Front Fork Parts Inspection in Section 2B (Page 2B-9)".

Rear Suspension Inspection
Inspect rear suspension
Every 12 000 km (7 500 miles, 24 months)
Inspect the rear shock absorbers for oil leakage and

Replace any defective parts, if necessary. Refer to "Rear
Shock Absorber Removal and Installation in Section 2C
(Page 2C-3)", "Cushion Lever Removal and Installation
in Section 2C (Page 2C-6)" and "Swingarm / Cushion
