equipment is increased to 30 kg to account for outriggers.

       2.16. "Mass in running order" means the sum of the unladen vehicle mass and driver mass.

       2.17. "Peak braking coefficient (PBC)" means the measure of tyre to road surface friction based on the maximum deceleration of a rolling tyre.

       2.18. "Power-assisted braking system" means a brake system in which the energy necessary to produce the braking force is supplied by the physical effort of the rider assisted by one or more energy supplying devices, for example vacuum assisted (with vacuum booster).

       2.19. "Secondary brake system" means the second service brake system on a vehicle equipped with a combined brake system.

       2.20. "Service brake system" means a brake system which is used for slowing the vehicle when in motion.

       2.21. "Single brake system" means a brake system which acts on only one axle.

       2.22. "Split service brake system (SSBS)" means a brake system that operates the brakes on all wheels, consisting of two or more subsystems actuated by a single control designed so that a single failure in any subsystem (such as a leakage type failure of a hydraulic subsystem) does not impair the operation of any other subsystem.

       2.23. "Stopping distance" means the distance travelled by the vehicle from the point the rider begins to actuate the brake control to the point at which the vehicle reaches a full stop.  For tests where the simultaneous actuation of two controls is specified, the distance travelled is taken from the point the first control is actuated.

       2.24. "Test speed" means the vehicle speed measured the moment the driver begins to actuate the brake control(s).  For tests where the simultaneous actuation of two controls is specified, the vehicle speed is taken from the point the first control is actuated.

       2.25. "Transmission" means the combination of components that provide the functional link between the control and the brake.

       2.26. "Unladen vehicle mass" means the nominal mass of the vehicle as indicated by the manufacturer(s) including all factory fitted equipment for normal operation of that vehicle (e.g. fire extinguisher, tools, spare wheel), plus coolant, oils, 90 per cent of fuel and 100 per cent of other gas or liquids, as specified by the manufacturer.

       2.27. "Vehicle type" means a sub-category of L-category vehicles which do not differ in such essential respects as:

 (a) The vehicle category, as defined in the Consolidated Resolution (R.E.3);

 (b) The gross vehicle mass, as defined in paragraph 2.12.;

 (c) The distribution of the mass between the axles;

 (d) Vmax;

 (e) A different type of braking device;

 (f) The number and arrangement of the axles;

 (g) The engine type;

 (h) The number and ratios of gears;

 (i) The final drive ratios;
