Motorcycle Vehicle Knowledge and Maintenance
What the exam tests
This domain checks pre-ride checks, basic maintenance and knowing when a motorcycle is not roadworthy. Questions ask about tyres, chain, brakes, lights, fluids and inspection intervals.
Pre-ride check
- Tyres: minimum tread depth is 1.6 mm for a motorcycle; check pressure cold and look for cuts, bulges and embedded objects.
- Chain: correct slack per the manual (often 20–30 mm), lubricated, no tight spots; too tight stresses the gearbox and wheel bearings.
- Brakes: lever and pedal feel firm, pads above the wear limit, no leaking fluid; brake fluid absorbs moisture and should be changed on schedule.
- Lights, horn, indicators, mirrors and reflectors all working.
- Steering, suspension, wheel bearings and spokes: no play, no oil leaks.
- Engine oil and coolant at the correct level; check for fuel or oil leaks after standing.
Inspection and documents
Motorcycles in Norway are due for EU-kontroll (periodic inspection) first four years after first registration, then every two years. Keep the registration document and proof of insurance available.
Worked example
A rider notices the chain looks tight after fitting a larger rear sprocket. Correct reasoning: an over-tight chain limits suspension travel and can destroy the countershaft bearing, so adjust to the manual's slack with the bike on its side stand or as specified, then recheck.
Traps
Checking tyre pressure after a ride when tyres are hot; ignoring a spongy brake lever; using car engine oil with the wrong specification; assuming a low-mileage bike needs no fluid changes.
