2 Definitions
Handling characteristics for the purpose of this unit standard, refer to how a road motorcycle behaves as a result of the interaction of its design and the dynamics present at the time.
Motorcycle dynamics refer to the motion of a road motorcycle, and the interaction of the various physical forces that affect that motion.
Element 1
Demonstrate knowledge of the operation of major components and systems of road motorcycles.
Performance criteria
1.1 Road motorcycle engine performance and characteristics are described.
Range performance – power, power band, torque, torque range; characteristics
– 2-stroke, 4-stroke, cylinder layout, transverse mountings, in-line mounting.
1.2 Operation of transmission system is described in terms of clutch, gearbox, and drivetrain.
Range clutch – engagement point, clutch slippage; gearbox
– relationship between engine RPM and motorcycle speed, the leverage effect of the gears; drivetrain – chain drive, belt drive, shaft drive.
1.3 Road motorcycle braking systems and types are described in terms of their operation.
Range systems
– ABS, non-ABS, linked; types – disc, drum.
1.4 Road motorcycle steering geometry is described.
Range rake, trail, turning circle.
1.5 Operation and benefits of the road motorcycle suspension system are described in terms of spring pre-load, rebound damping, and suspension travel.
1.6 Tyre factors are described in terms of effect on the handling characteristics of road motorcycles and adhesion.
Range inflation, tread type, wear, new tyres.
1.7 The functions of road motorcycle warning lights, gauges, instruments, and controls are described.

Element 2
Describe the dynamics of road motorcycles.
Performance criteria
2.1 Dynamics of road motorcycles in straight line motion are described in terms of contributing factors.
Range mass, mass distribution, centre of mass, effects of gravity, traction, kinetic energy, velocity, weight transfer under acceleration and deceleration.
2.2 Dynamics of road motorcycles while cornering are described in terms of contributing factors.
Range mass, mass distribution, centre of mass, effects of gravity, traction, kinetic energy, centrifugal force, centripetal force, gyroscopic effects, velocity, effects of acceleration and deceleration, effects of braking, countersteering.
Element 3
Describe the handling characteristics of road motorcycles.
Performance criteria
3.1 Handling characteristics of road motorcycles are described in terms of response to combined effects of, and variations in, suspension, tyres, loading, aerodynamics, road surface, rider weight transfer, and speed.
3.2 Handling characteristics of road motorcycles are described in terms of lateral stability, dynamics, and speed.
Range cornering, straight line motion.
3.3 Handling characteristics of road motorcycles are described in terms of longitudinal and lateral stability.
Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.
