Refer to Important Safety Precautions on page 33.
Keeping the wheels true (round) and maintaining
correct spoke tension are critical to safe
motorcycle operation. During the first few rides,
spokes will loosen more rapidly due to the initial
seating
of the parts. Excessively loose spokes may
result in instability at high speeds and the possible
loss of control.
It is not necessary to remove the wheels to perform
the recommended service in the Maintenance
Schedule (pages 36, 37).
However, information for wheel removal is
provided for emergency situations (page 167).
1. Inspect the wheel rims (1) and spokes (2) for
damage.
2. Tighten, any loose spokes to the specified
torque:
Spokes: 2.7 lbf·ft (3.7 N·m, 0.4 kgf·m)
3. Check wheel rim runout. If runout is
noticeable, see an official Honda Service
Manual for inspection instructions.
Also inspect the valve stems for their positions. A
tilted valve stem indicates the tube is slipping
inside the tire or the tire is slipping on the rim. See
your dealer.
See an official Honda Service Manual for
inspection information:
1. Check the axle shaft for runout.
2. Check the condition of the wheel bearings.
