b. The height of the wear mark on the tread protrusion is
1.6mm (0.06 in). The triangle (
△
T.W.I.) mark on the sidewall
indicates the location of the wear bar. If the wear reaches the
mark point, it means that it has been worn to the limit. If you
continue to drive, there will be a safety hazard. You must
replace with new tires of the same specification.
c. The inspection of the rear tires is the same as that of the
front tires and will not be repeated here.
2. Replace tires
a. Replace the front tire
The front wheel assembly can be removed by referring to
the description of the steps for disassembling the front wheel
assembly in the "Front Fork Assembly" of this manual. Use a
tyre picker to remove the tire. When disassembling, pay
attention to avoiding the valve position. Do not use a
crowbar to pry the tire at the valve position to avoid damage
to the tire pressure sensor. Before pressing the tire, install it
according to the direction of rotation indicated by the
sidewall, and aim the light point with the yellow mark at the
position of the valve. After replacing a new tire or repairing a
tire, the dynamic balance needs to be re-balanced to prevent
the front wheel from shaking due to unbalance and affecting
the driving experience
b. Replace the rear tire
Refer to the previous operation of replacing the rear brake
disc to remove the rear wheel assembly. Other operations
are similar to the replacement of the front tires, and will not
be repeated here.
Steering mechanism
Caution:
●Regularly inspect the steering mechanism according to the
requirements of the regular maintenance table.
●Park the vehicle on a flat and stable ground or a lifting
platform, and put down the main support.
●Too small steering mechanism clearance will cause
inflexible steering and accelerate bearing wear. When it is
too large, it will cause driving jitter and abnormal noise when
braking.
1. Check the steering mechanism
a. Support the front wheel with a suitable tool so that the
front tire is hung in the air and then rotate the direction
handle left and right to confirm whether the rotation is
flexible and smooth; whether the cable and cable show signs
of being pulled.
b. Keep the front wheel suspended, shake the front wheel
assembly in multiple directions, to confirm whether the front
fork assembly is axially strung or loosened in the radial
direction.
2. Adjust the steering mechanism
If the steering is not flexible or loose, the axial bearing
clearance should be adjusted.
Refer to the steps to remove the faucet lock in the section
"Replace the lower link plate" in the "Front Fork Assembly" of
this manual, and remove the storage box. Remove the faucet
lock.
b. For the convenience of explanation, other parts are
hidden here. First use a 38-42 hook wrench with a thickness
of 6mm (0.24 in) to loosen the adjusting nut (1a); move the
lock washer

up and then loosen the adjusting nut (1b).
c. If the steering is heavy, loosen the adjusting nut (1c)
counterclockwise. First screw it clockwise to 35N.m (3.6
kgf.m, 26 lbf.ft), then loosen 1/4 turn counterclockwise, and
then screw it to 15N.m (1.2 kgf.m, 11 lbf.ft).
d. If thre is any looseness, screw it clockwise to 35N.m (3.6
kgf.m, 26 lbf.ft), then loosen it counterclockwise by 1/4 turn,
and then screw it to 15N.m (1.2 kgf.m, 11 lbf. ft).
e. After adjustment, confirm whether the steering is
restored. If it returns to normal, turn the nut (1b) clockwise
