1. What is the primary purpose of a motorcycle’s clutch?
A. To increase engine power
B. To slow down the motorcycle
C. To disengage the engine from the transmission
D. To lubricate the gearbox
Rationale: The clutch allows the rider to temporarily disconnect the
engine from the transmission to shift gears smoothly.
2. What is the typical spark plug gap for most motorcycles?
A. 0.2–0.3 mm
B. 0.4–0.5 mm
C. 0.6–0.8 mm
D. 1.0–1.2 mm
Rationale: Most motorcycles require a spark plug gap of 0.6–0.8 mm
to ensure proper ignition and efficient combustion.
3. Which component controls the mixture of fuel and air in a carbureted
motorcycle engine?
A. Fuel injector
B. Carburetor
C. Ignition coil
D. Throttle cable
Rationale: The carburetor mixes the correct ratio of fuel and air for
combustion in the engine.
4. What is the function of the flywheel in a motorcycle engine?
A. To increase fuel efficiency
B. To maintain engine momentum between power strokes
C. To start the engine
, D. To regulate oil flow
Rationale: The flywheel stores rotational energy to smooth out the
power delivery from the engine.
5. What type of oil is commonly used in a wet-clutch motorcycle?
A. SAE 10W-30 automotive oil
B. Hydraulic oil
C. Motorcycle-specific oil labeled for wet clutches
D. Gear oil
Rationale: Wet-clutch motorcycles require special oil that lubricates
the engine while preventing clutch slippage.
6. What is the main advantage of a shaft-driven motorcycle over a chain-
driven motorcycle?
A. Higher top speed
B. Lower production cost
C. Less maintenance
D. Lighter weight
Rationale: Shaft drives require less maintenance than chains or belts
and are more durable over time.
7. Which type of braking system is commonly found on modern
motorcycles?
A. Drum brakes only
B. Hydraulic disc brakes
C. Mechanical disc brakes
D. Regenerative brakes
Rationale: Most modern motorcycles use hydraulic disc brakes for
superior stopping power and control.
8. What is the correct procedure when measuring valve clearances on a
four-stroke engine?
A. Measure with the engine running
B. Measure with the engine cold and valves closed
C. Measure with the engine hot and ignition on
D. Measure with the carburetor removed
Rationale: Valve clearances must be measured when the engine is
cold to avoid thermal expansion affecting the measurement.
9. What does a motorcycle’s CDI (Capacitor Discharge Ignition) unit do?
A. Controls fuel injection
B. Controls ignition timing
, C. Regulates battery voltage
D. Opens and closes valves
Rationale: The CDI controls the timing and firing of the spark plugs
to ignite the fuel-air mixture.
10. Which type of suspension is commonly used on the rear of most
motorcycles?
A. Leaf spring
B. Torsion bar
C. Swingarm with shock absorbers
D. Airbag suspension
Rationale: The swingarm with shocks is standard on most
motorcycles, providing stability and comfort.
11. When replacing a motorcycle chain, what should be checked to
ensure proper installation?
A. Engine compression
B. Chain tension and alignment
C. Brake fluid level
D. Tire pressure
Rationale: Proper chain tension and alignment are crucial to prevent
premature wear and unsafe riding conditions.
12. What is the function of the motorcycle regulator/rectifier?
A. Convert AC to DC and regulate voltage to the battery
B. Adjust fuel mixture
C. Control exhaust emissions
D. Operate the starter motor
Rationale: The regulator/rectifier converts the alternator’s AC output
to DC and regulates voltage for charging the battery safely.
13. Which of the following tools is specifically used to measure
piston ring end gap?
A. Torque wrench
B. Caliper
C. Micrometer
D. Feeler gauge
Rationale: A feeler gauge measures the gap at the ends of piston
rings to ensure proper engine compression.
14. What is the purpose of a motorcycle’s air filter?
A. Cool the engine
