2-24 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
Measure the tread depth at the center of the tread with a
depth gauge [A]. Since the tire may wear unevenly, take
measurement at several places.
If any measurement is less than the service limit, replace
the tire (see Tire Removal/Installation in the Wheels/Tires
4.5 mm (0.18 in.)
7.4 mm (0.29 in.)
1 mm (0.04 in.)
(AT, CH, DE) 1.6 mm (0.06 in.)
2 mm (0.08 in.)
(Up to 130 km/h (80 mph))
3 mm (0.12 in.)
(Over 130 km/h (80 mph))
Some replacement tires may adversely affect han-
dling and cause an accident resulting in serious in-
jury or death. To ensure proper handling and sta-
bility, use only the recommended standard tires for
replacement, inflated to the standard pressure.
Most countries may have their own regulations a mini-
mum tire tread depth; be sure to follow them.
Check and balance the wheel when a tire is replaced
with a new one.
Wheel Bearing Damage Inspection
Raise the front wheel off the ground with jack (see Front
Wheel Removal in the Wheels/Tires chapter).
Turn the handlebar all the way to the right or left.
Inspect the roughness of the front wheel bearing by mov-
ing [A] the wheel to be both side.
Spin the front wheel lightly, and check for smoothly turn,
roughness, binding or noise.
If roughness, binding or noise is found, remove the front
wheel (see Front Wheel Removal in the Wheels/Tires
chapter) and inspect the wheel bearing (see Hub Bearing
Inspection in the Wheels/Tires chapter).
