|Information||Method of Inspection||Reason for rejection|
check need not be carried out if either the front or
rear wheels have already been failed under Section 4.2 for
unacceptable buckling, eccentricity or damage.
A clamp may be used if available, provided it does not obstruct the straight edge or cord.
If misalignment is considered excessive, a road test may be conducted at the tester's discretion, to assess the effect on the handling of the motor bicycle (see Introduction Item 10).
Some shaft driven motor bicycles and those motor bicycles which have been adapted for use with a side car may have a certain amount of parallel misalignment.
1. Using a wheel clamp or an assistant ensure that the front
wheel is held upright and inline with the frame
a. place a straight edge or cord against the rear tyre parallel to it and as high off the ground as other parts will permit
b. estimate the gap (if any) between the straight edge or cord at the rear points where it is opposite the front tyre
c. move the straight edge or cord to the other side of the motor cycle and repeat 1a and 1b above
d. sight along the front wheel and forks and assess any misalignment.
1. Any misalignment which is sufficient to adversely affect
the handling or steering of the motor bicycle.
