TIRE INFLATION

1

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

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

1

WARNING

1

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.
