Motorcycle Controls and Vehicle Knowledge

You need to know what each control does and how the machine behaves when it is used. The right hand controls the front brake and throttle; the left hand operates the clutch; the right foot works the rear brake; the left foot changes gear (one down, the rest up on most bikes). The front brake provides most of the stopping power because weight transfers forward - but grabbing it on a wet or gravelly surface can lock the wheel. Progressive, smooth application of both brakes together is the standard technique.

Understand the systems too: the chain or belt needs correct tension and lubrication, tyres need correct pressure and legal tread, and brakes, lights, and fluid levels need regular checks. A pre-ride check (often remembered as a walk-around: tyres, controls, lights, chain, fluids) catches problems before they become emergencies. Know what a tyre pressure that is too low does - heavier steering, longer stopping, faster wear - and what worn tread means for grip in the wet.

Trap: questions about braking often bait you into choosing "front brake only" or "rear brake only". The correct answer is normally both, applied progressively. Rule of thumb: squeeze, do not grab. Worked example: you are riding in rain and need to slow for a bend. Roll off the throttle, apply both brakes gently and progressively, and avoid sudden steering inputs - smoothness keeps the tyres within their grip.
