Motorcycle Chassis 1

A rider complains of front wheel patter that gets worse as the motorcycles speed increases. This most likely indicates

• the rebound damping is insufficient

• the front tyre pressure is too high

• the steering head bearings are over-tight

• the front wheel need balancing

A variable rate front fork spring is one that:

• has different coil thickness one end

• has a tighter spring coil pitch at one end

• can be adjusted using the pre-load adjuster

• is fitted underneath the damper cartridge

Limited progressive rear suspension is achieved on a twin shock absorber motorcycle by:

• inverting the shock absorbers

• fitting gas shock absorbers

• inclining the shock absorbers in relation to the swinging arm

• making the shock absorbers perpendicular to the swinging arm

Which component controls road spring bounce?

• The damper

• The spring

• The ball joint

• The hub

The MAIN purpose of a damper is to:

• limit the maximum travel of the suspension

• absorb the movement energy of the spring

• maintain motorcycle height under load

• allow for excess load

It is good practice after fitting brake pads to inform the customer to:

• brake as hard as possible

• check the brake fluid level

• check the tightness of the wheel bolts

• avoid hard braking until the pads have bedded in

To meet legal requirements on a 125cc motorcycle, the tyre should have:

• not less than 1.6 millimeters of tread across 75% of the breadth and around the circumference

• not less than 1 millimeter of tread across 75% of the breadth and around the circumference

• a clearly visible tread pattern around the whole circumference and across the breadth of the tread

• a clearly visible tread pattern around the whole circumference and across 75% of the breadth of tread

The gas normally used in rear gas shock absorbers is:

• nitrogen

• helium

• argon

• oxygen

Shaft drive motorcycles often have the tendancy

• For the rear suspension to compress under accleration

• To torque steer under acceleration

• For the rear suspension to extend under acceleration

• to torque steer under deceleration
