2.5 Wheel Alignment (Solo machine)
|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 should be used if available. provided It does not obstruct the straight edge or cord.
If the misalignment is considered excessive, a road test may be conducted, at the tester's discretion, to access the effect on the handling of the machine (Reference Page 1, paragraph 5).
Some shaft drive machines and those machines which have been adapted for use with side car may have a certain amount of parallel misalignment as standard.
Using a wheel clamp or an assistant
ensure that the front wheel is held upright and in line 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 (ie silencers, frame etc) 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 I a. and 1 b. above;
2. 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 machine.
