TIRE INFLATION

WARNING
1
WARNING
Do not inflate any tire beyond its maximum inflation pres-
sure as specified on tire sidewall. Overinflation may
cause tire to suddenly deflate which could result in death
or serious injury.
Check tire pressure and tread:
● Before every ride.
● At the 1000 mile (1600 km) service interval.
●
At every scheduled service interval.
Check for proper front and rear tire pressures when tires are
cold. Compare pressure against
Table 1-6.
TIRE REPLACEMENT
Treadwear indicator bars will appear on tire tread surfaces
when 1/32 in. (0.794 mm) or less of tire tread remains.
Arrows on tire sidewalls pinpoint location of wear bar indica-
tors. Always remove tires from service before they reach the
tread wear indicator bars (1/32 in. [0.794 mm] tread pattern
depth remaining).
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

WARNING

WARNING
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 front wheel bearing:
●
At every 5000 mile (8000 km) service interval.
Check rear wheel bearing:
●
At every 10,000 mile (16,000 km) service interval.
Check wheel bearings for wear and corrosion. Excessive play
or roughness indicates worn bearings. Replace bearings in
sets only.
