ADJUSTING THE TOE-IN
***********************************************
Toe-in measurement steps:
NOTE:
Before measuring the toe-in, make sure that
the tire pressure is correct.
Mark both front tire tread centers.
Raise the front end of the machine so that
there is no weight on the front tires.
Face the handlebar straight ahead.
Measure the width È between the marks.
Rotate the front tires 180° until the marks are
exactly opposite one another.
Measure the width É between the marks.
Calculate the toe-in using the formula given
below.
Toe-in = É – È
If the toe-in is incorrect, adjust it.

Toe-in
WARNING
Be sure that both tie-rods are turned the
same amount. If not, the machine will drift
right or left even though the handlebar is
positioned straight. This may lead to mis-
handling and an accident.
After setting the toe-in to specification, run
the machine slowly for some distance with
both hands lightly holding the handlebar
and check that the handlebar responds cor-
rectly. If not, turn either the right or left tie-
rod within the toe-in specification.
