Motorcycle Controls and Pre-Ride Inspection
Motorcycle Controls and Pre-Ride Inspection
This domain tests whether you can find and operate every control without looking down, and whether you inspect the motorcycle before each ride. On Guam's roads, a loose chain, a low tire, or a failed brake light can turn a short trip into a crash. The exam expects a repeatable pre-ride routine, not a vague "look it over."
Know the controls by feel
- Right hand: throttle, front-brake lever, engine cut-off switch.
- Left hand: clutch lever on a manual, turn signals, horn, high/low-beam switch.
- Right foot: rear-brake pedal. Left foot: shift lever.
- Scooters and automatics vary; confirm the layout before riding an unfamiliar machine.
- The front brake supplies most stopping power. Use both brakes smoothly, not the rear alone.
Pre-ride inspection: a repeatable checklist
Use T-CLOCS or a similar order: Tires and wheels (pressure, tread, cracks, spokes); Controls (levers, cables, throttle snap, steering); Lights and electrics (headlight, taillight, brake light, signals, horn); Oil, fluids, and fuel (level, leaks); Chassis (suspension, chain/belt tension, fasteners); Stands (side stand spring, mirrors, load).
Check the brake light with both the hand lever and the foot pedal. A light that works only one way is a defect. Check tire pressure cold, not after a ride. Chain slack should match the owner's manual; too tight damages bearings, too loose can derail.
Worked example
A rider squeezes the front-brake lever and it travels almost to the grip, feeling spongy. Reasoning: a firm lever should stop travel early. Spongy feel points to air or moisture in the hydraulic line, a leak, or low fluid. The correct action is not to ride; inspect the reservoir and lines, and have the brake bled or repaired. A test ride around the block is not a diagnosis.
Traps that cost marks
- Checking only the tires and calling it an inspection.
- Forgetting the brake light or horn.
- Overfilling oil or ignoring a fuel leak.
- Assuming a scooter has the same controls as a manual motorcycle.
- Inspecting after the engine is running and hot.
