CHECKING THE TIRES

1. Measure:

• tire pressure (cold tire pressure)

Out of specification → Adjust.

NOTE:

• The tire pressure gauge 1 is included as

standard equipment.

• If dust or the like is stuck to this gauge, it will

not provide the correct readings. Therefore,

take two measurements of the tire’s pressure

and use the second reading.

WARNING

Uneven or improper tire pressure may

adversely affect the handling of this vehicle

and may cause loss of control.

• Maintain proper tire pressures.

• Set tire pressures when the tires are cold.

• Tire pressures must be equal in both front

tires and equal in both rear tires.

2. Check:

• tire surfaces

Wear/damage → Replace.

WARNING

It is dangerous to ride with a worn-out tire.

When tire wear is out of specification,

replace the tire immediately.
