2.1 Steering Control

Information Method of Inspection Reason for rejection
Rubber mounted handlebars

Handlebars on some machines are rubber mounted. Some movement may be detected when firm pressure is applied to handlebars secured in this way
1. With the wheels supporting the weight of the machine grasp the handlebars by the grips and by the application of firm pressure check for movement at the grips, clamps or any weakness of the handlebars or fork yokes.

2. With the front wheel clear of the ground, turn the steering from lock to lock to check that:

a. there is no fouling between moving and fixed parts;

b. the handlebar grips do not come so close to a fixed part (e.g. fuel tank or fairing) as to impede the operation of the controls.

c. the control cables are not pulled taut on full lock and that they are not likely to be trapped or caught on a projection

d. any steering damper fitted is properly secured, effective and is not likely to impede control of the motor bicycle

e. fairings or leg shields do not impede the steering.

3. Examine steering lock stops (if fitted).

4. Check for any change in the engine speed with the front wheel on the ground, the engine running and turning the steering from lock to lock.
a. handlebar clamps not tight, or any bolt loose or missing (see information column.)

b. handlebar or fork yoke deformed, fractured, cracked or excessively corroded

c. handgrips missing or not secure to handlebars d. an excessively deteriorated handlebar flexible mounting

a. any fouling between components which would interfere with the free movement of the steering from lock to lock

b. insufficient clearance at either full lock position for the handlebar grips to be properly grasped or the controls to be properly operated

c. restriction to the movement of the handlebars by cables being pulled taut, becoming trapped or by being caught on a projection

d. a steering damper which is insecure, ineffective or in such a condition that the steering action is impaired. (see Sub-Section 2.2 information column)

e. any fairing or leg shield insecure or so located it is likely to impede the steering.

3. A loose, missing, maladjusted, or ineffective steering lock stop.

4. A significant change in engine speed.
