TIRE INFLATION
1WARNING1WARNING
Do not inflate tire beyond maximum pressure as speci-
fied on sidewall. Over inflated tires can blow out, which
could result in death or serious injury. (00027a)
Check tire pressure and tread:
● Before every ride.
Check for proper front and rear tire pressures when tires are
cold. Compare pressure against Ta ble 1-7.
TIRE REPLACEMENT
See Figure 1-18. Arrows on tire sidewall pinpoint location of
wear bar indicators on the tire tread. Tire wear indicator bars
will appear on tire tread surfaces when 1/32 in. (0.8 mm) or
less of tire tread remains.
Replace the tires when the tire wear indicator bars appear.
New tires are needed if any of the following conditions exist.
1. Tire wear indicator bars become visible on the tread sur-
faces.
2. Tire cords or fabric become visible through cracked side-
walls, snags or deep cuts.
3. A bump, bulge or split in the tire.
4. Puncture, cut or other damage to the tire that cannot be
repaired.
WHEEL BEARINGS
1WARNING1WARNING
Never use compressed air to “spin-dry” bearings. Very
high bearing speeds can damage unlubricated bearings.
Spinning bearings with compressed air can also cause a
bearing to fly apart, which could result in death or seri-
ous injury.
Check front and rear wheel bearings for wear:
● Every time a wheel is removed.
● When storing or removing the motorcycle for the season.
Check wheel bearings for wear and corrosion. Excessive play
or roughness indicates worn bearings. Replace bearings in
sets only.
