Question 1
Should the clutch control lever normally have some free play?
ANo.
BYes, approximately 2 to 3 mm.
Why — Explanation
A small free play at the clutch lever, about 2 to 3 mm, guarantees that the clutch engages fully and does not slip.

Question 2
When lit, the green warning light marked N on the instrument panel tells the rider that:
AThe battery is charging correctly.
BNo gear is selected in the gearbox.
CA direction indicator light is switched on.
Why — Explanation
The green N light is the neutral indicator: it shows the gearbox is in neutral, with no gear engaged.
Question 3
On motorcycles, the function of the position light (luz de presença) is to:
AIdentify the motorcycle at a distance of 30 metres.
BMake it possible to signal the presence of the motorcycle at a distance of 100 metres.
CMake it possible to signal the presence of the motorcycle at a distance of 150 metres.
Why — Explanation
The position light makes the motorcycle visible to other road users from at least 150 metres away.
Question 4
Checking and topping up the coolant of a motorcycle should be done with:
AThe engine running and cold.
BThe engine running at approximately 2,500 revolutions per minute and at a temperature of 72º C.
CThe engine stopped and cold.
Why — Explanation
Coolant must be checked with the engine stopped and cold, which gives an accurate reading and avoids burns from hot, pressurised liquid.
Question 5
How should the engine oil level of a motorcycle be checked?
AWith the engine running and the vehicle resting on its stand.
BWith the engine stopped and cold, and the vehicle held upright.
CWith the engine stopped, preferably cold, and the vehicle resting on its stand.
Why — Explanation
The oil level is read with the engine stopped and cold and the motorcycle held vertical, so the oil settles and the reading is correct.
Question 6
On some motorcycles it is possible to adjust the reach of the front brake and clutch levers. This adjustment should be carried out:
ADirectly by the rider.
BBy the manufacturer, only when the vehicle is set up as new.
COnly in a specialised workshop.
Why — Explanation
The levers have built-in reach adjusters so the rider can set them to suit hand size, without a workshop visit.
Question 7
When riding a motorcycle, downshifts should be made with the least possible strain on the engine, so:
AA downshift should only be made when the engine no longer responds to the throttle.
BSignificant throttle should be applied while the clutch is pulled in.
CIt is advisable to pull the clutch in fully before selecting another gear.
Why — Explanation
Fully disengaging the clutch before selecting a lower gear lets the engine and gearbox speeds match smoothly and protects the transmission.
Question 8
On motorcycles with a rear monoshock (single suspension unit), can the spring preload normally be adjusted?
ANo.
BYes, but only at the factory.
CYes.
Why — Explanation
Rear monoshock units have an adjustable preload ring, so the rider can set the spring preload for load and riding conditions.
Question 9
On motorcycles fitted with a hydraulic clutch, the fluid level should be checked:
AOnly when the new vehicle is delivered, as it needs no maintenance.
BPeriodically, by the rider.
COnly in a specialised workshop.
Why — Explanation
Hydraulic clutch fluid can drop over time, so the rider should check the reservoir level regularly.
Question 10
In two-stroke engines, only petrol mixed with oil can be used.
AThe statement is false.
BThe statement is true.
Why — Explanation
A two-stroke engine has no separate oil sump, so the petrol and oil mixture lubricates its internal parts.
Question 11
On a motorcycle, the braking distance can vary due to:
AThe slope of the road.
BThe power of the vehicle's engine.
CThe condition of the tyres.
Why — Explanation
Worn or incorrectly inflated tyres reduce grip and directly lengthen the braking distance.
Question 12
The emergency engine cut-off switch on a motorcycle has the function of:
APreventing the motorcycle from spilling petrol and catching fire if it falls over.
BStopping the engine and, at the same time, deactivating the whole electrical system.
CStopping the engine.
Why — Explanation
The emergency cut-off switch (interruptor de paragem de emergência) only stops the engine, so the rider can switch it off quickly in an emergency.
Question 13
The engine shown in the figure is:
AA two-cylinder engine.
BA single-cylinder engine.
CA four-cylinder engine.
Why — Explanation
The engine in the figure has a single cylinder, so it is a single-cylinder (monocilíndrico) engine.
Question 14
The engine shown in the figure has:
ATwo pistons.
BThree pistons.
COne piston.
Why — Explanation
The figure shows a single-cylinder engine, which has one piston (êmbolo).
Question 15
The rear wheel brake of a motorcycle should be operated by the rider:
AWith the right hand.
BWith the left foot.
CAlways with the right foot.
Why — Explanation
On a motorcycle the rear brake is applied with the right foot pedal, while the right hand operates the front brake lever.
Question 16
If the clutch lever has 7 to 8 mm of free play, what should be done?
ATurn the threaded adjuster or the numbered disc so the free play is significantly lower.
BTake the vehicle to a specialised workshop for immediate repair, as only there can the problem be solved.
CNo adjustment is needed, as this amount of free play is correct.
Why — Explanation
The correct free play is about 2 to 3 mm, so with 7 to 8 mm the rider should use the adjuster or numbered disc to reduce it.
Question 17
As a rule, the front suspension of a motorcycle has:
ATwo shock absorbers.
BOne shock absorber and one spring.
COne shock absorber.
Why — Explanation
The front fork of a motorcycle normally has two suspension legs, one on each side of the wheel.
Question 18
As a rule, the rear suspension of a motorcycle has:
ATwo springs.
BThree springs.
COne spring.
Why — Explanation
Most motorcycles use a single rear spring and damper unit (monoshock).
Question 19
As a rule, motorcycles use disc brakes because they provide:
ABetter braking.
BBetter steering.
CHigher speed.
Why — Explanation
Disc brakes (travões de disco) dissipate heat well and give stronger, more consistent braking than drum brakes.
Question 20
What is the lubrication process of a two-stroke engine?
AThe oil held in the engine crankcase is pumped through the lubrication circuit.
BThe use of a lubrication system in which the oil is carried in suspension in the fuel.
CThe use of the crankcase as an oil reservoir.
Why — Explanation
In a two-stroke engine the oil is mixed with the petrol and carried in suspension, lubricating the moving parts as the mixture passes through the engine.
