Tire RotationNES00019
CAUTION:

is fixed in each tire.
DESCRIPTION
Safety Device Preventing from Being Incorrectly Installed
Front brake disc rotor and front wheel
Front and rear wheel size for this model differs, therefore a special pin has been installed on the front
brake disc rotor. To accommodate this pin a hole has been provided on the front wheel (the rear wheel
does not have this hole.) and in some case the rear wheel is being mistakenly installed on the front.
Maximum allowable
unbalanceDynamic (At rim flange) 5 g (0.17 oz) (one side)
Static (At rim flange) 10 g (0.35 oz)
