Tire; Steering; Tire Tread Depth - Suzuki VZ800 Service Manual

TIRE

Inspect every 6 000 km (4 000 miles, 12 months).
TIRE TREAD CONDITION
Operating the motorcycle with excessively worn tires will
decrease riding stability and consequently invite a dangerous
situation. It is highly recommended to replace a tire when the
remaining depth of tire tread reaches the following specification.
 09900-20805: Tire depth gauge
 Tire tread depth
Service Limit (FRONT) : 1.6 mm (0.06 in)
(REAR) : 2.0 mm (0.08 in)
TIRE PRESSURE
If the tire pressure is too high or too low, steering will be
adversely affected and tire wear increased. Therefore, maintain
the correct tire pressure for good roadability or shorter tire life
will result. Cold inflation tire pressure is as follows.


The standard tire fitted on this motorcycle is
130/90-16M/C (67H) for front and 170/80-15M/C (77H)
for rear. The use of tires other than those specified
may cause instability. It is highly recommended to use
a SUZUKI Genuine Tire.

STEERING

Inspect initially at 1 000 km (600 miles, 2 months) and
every 12 000 km (7 500 miles, 24 months) thereafter.
Steering should be adjusted properly for smooth turning of han-
dlebars and safe running. Overtighten steering prevents smooth
turning of the handlebars and too loose steering will cause poor
stability. Check that there is no play in the steering stem while
grasping the lower fork tubes by supporting the machine so that
the front wheel is off the ground, with the wheel straight ahead,
and pull forward. If play is found, perform steering bearing
adjustment as described in page 8-24 of this manual.
