Vehicle safety inspection and maintenance for motorcycles
Vehicle safety inspection and maintenance for motorcycles tests whether a rider can spot a machine that is unfit before it fails. The exam covers daily checks, wear items, legal modifications, and the inspection cycle; the theme is prevention, not repair after a breakdown.
Core checks
- Tyres: correct cold pressure, legal tread depth, no cuts, bulges, or embedded objects. Replace tyres that reach the wear indicator or show cracking.
- Brakes: check lever and pedal travel, pad thickness, fluid level, and leaks; test at low speed before entering traffic.
- Lights and electrics: headlight, tail light, brake light, indicators, horn, and battery terminals. A failed brake light is a safety defect, not a cosmetic issue.
- Steering and suspension: check head bearings for play, fork seals for leaks, and rear suspension for damage.
- Chain and sprockets: check slack against the manufacturer’s specification, lubricate regularly, and replace worn sprocket teeth. Too tight a chain damages bearings; too loose a chain can jump off.
- Fluids and filters: engine oil, coolant where fitted, brake fluid, and air filter. Fix leaks before riding.
- Mirrors and controls: adjust mirrors, check throttle return, clutch and brake operation, and ensure nothing obstructs the handlebars.
Legal and maintenance points
Do not fit illegal exhausts, high-intensity lights, or engine modifications; they can fail inspection and increase noise and risk. Follow the current inspection due date and applicable exemption conditions. Under the October 2022 inspection-cycle reform, eligible motorcycles undergo on-site inspection in registration years six and ten, with the inspection-mark procedure every two years within ten years; after ten years, on-site inspection is annual. Exemption eligibility and the actual recorded due date still need checking; do not substitute the older four-year/annual summary for the current process. Keep the helmet clean and undamaged; replace it after a serious impact.
Worked example
A rider finds the chain has about 10 mm of slack when the specification is 25–35 mm, and the sprocket teeth are hooked. The correct action is to replace the chain and sprocket set, not simply tighten the chain. Reasoning: a tight chain overloads the output bearing, while hooked teeth accelerate wear and can cause the chain to jump under load.
Traps that cost marks
- Setting tyre pressure to the maximum on the sidewall rather than the recommended cold pressure.
- Ignoring a brake light because the headlight works.
- Tightening a worn chain instead of replacing it.
- Treating an illegal exhaust as a personal choice; it is a compliance and noise issue.
