MOT Test Checks ref.27

About the MOT Test

In the UK, all vehicles more than three years old are subject to an annual test to ensure that they meet minimum safety requirements. A current test certificate must be issued before a machine can be used on public roads, and is required before a road fund licence can be issued. Riding without a current test certificate will also invalidate your insurance.

For most owners, the MOT test is an annual cause for anxiety, and this is largely due to owners not being sure what needs to be checked prior to submitting the motorcycle for testing. The simple answer is that a fully roadworthy motorcycle will have no difficulty in passing the test.

This is a guide to getting your motorcycle through the MOT test. Obviously it will not be possible to examine the motorcycle to the same standard as the professional MOT

tester, particularly in view of the equipment required for some of the checks. However, working through the following procedures will enable you to identify any problem areas before submitting the motorcycle for the test. It has only been possible to summarise the test requirements here, based on the regulations in force at the time of printing. Test standards are becoming increasingly stringent, although there are some exemptions for older vehicles. More information about the MOT test can be obtained from the TSO publications, How Safe is your Motorcycle and The MOT Inspection Manual for Motorcycle Testing-Many of the checks require that one of the wheels is raised off the ground. If the motorcycle doesn't have a centre stand, note that an auxiliary stand will be required. Additionally, the help of an assistant may prove useful.

Certain exceptions apply to machines under 50 cc, machines without a lighting system, and Classic bikes - if in doubt about any of the requirements listed below seek confirmation from an MOT tester prior to submitting the motorcycle for the test.

Check that the frame number is clearly visible.

HFA'J?U1"a component is in J-.-.Z.borderline condition, the HiIV Itester has discretion in

deciding whether to pass or fail it. If the motorcycle presentedis clean and evidently well cared for,the tester may be more inclined to pass a borderline component than if the motorcycle is scruffy and apparently neglected.

Electrical System

Lights, turn signals, horn and reflector

With the ignition on, check the operation
of the following electrical components. Note:
The electrical components on certain small-
capacity machines are powered by the
generator, requiring that the engine is run for
this check.

a) Headlight and tail light. Check that both illuminate in the low and high beam switch positions.

b) Position lights. Check that the front position (or sidelight) and tail light illuminate in this switch position.

c) Turn signals. Check that all flash at the con-ect rate, and that the warning lightfs) function correctly. Check that the turn signal switch works correctly.

d) Hazard warning system (where fitted). Check that all four turn signals flash in this switch position.

e) Brake stop light. Check that the light comes on when the front and rear brakes are independently applied. Models first used on or after 1st April 1986 must have a brake light switch on each brake.

f) Horn. Check that the sound is continuous and of reasonable volume.

• Check that there is a red reflector on the rear of the machine, either mounted separately or as part of the tail light lens.

• Check the condition of the headlight, tail light and turn signal lenses.

• The MOT tester will perform a headlight beam height check using specialised beam setting equipment (see illustration 1). This equipment will not be available to the home mechanic, but if you suspect that the headlight is incorrectly set or may have been maladjusted in the past, you can perform a rough test as follows.

• Position the bike in a straight line facing a brick wall. The bike must be off its stand, upright and with a rider seated. Measure the height from the ground to the centre of the headlight and mark a horizontal line on the wall at this height. Position the motorcycle 3.8 metres from the wall and draw a vertical
