Steering System

Checking Steering Clearance

●Lift the front wheel up from the ground with a jack.
Special Tool—Jack:
●When the front wheel faces ahead straightly and the front wheel is
off the ground, the whole handle shall be able to slide freely to the
left and right steering upper limits by the gravity action after the left
or right handle is pushed slightly.
★If the whole handle cannot slide freely to the left and right
steering upper limits, it indicates that the steering system is too tight.
●Push and pull the front fork to feel whether there is an excessive
clearance in the steering system.
★If you feel that the clearance is too loose, it indicates that the
steering system is too loose.
Remark
○The connection of cable and wire must be considered, because
they may also affect the movement of front fork.
○Make sure that the winding method of lead and cable is correct.
○The state of bearing must be good and the lubricant shall have
been added to the bearing, otherwise the detection result is invalid.
