Motorcycle Mechanical Knowledge, Maintenance and Equipment

Machine safety is your responsibility

Motorcycle mechanical knowledge, maintenance and equipment tests whether you can check your machine before a ride, recognise when something is wrong, and keep yourself and your passenger legal and protected.

Pre-ride checks

Use a simple walk-round: tyres, brakes, lights, horn, chain, oil, fuel, mirrors and steering.

  • Tyres: check pressure when cold against the handbook, look for cuts, bulges and worn tread; check both tyres.
  • Brakes: the lever and pedal should feel firm, not spongy; check pads and fluid level.
  • Chain: correct slack per the handbook, lubricated, no tight spots or missing O-rings; too tight damages bearings, too loose risks derailment.
  • Lights and horn: headlamp, brake light, indicators, horn.
  • Leaks and controls: look under the bike for oil or fuel; check throttle and clutch action.

Equipment and the law

You must wear a helmet that meets the approved standard and is correctly fastened; a loose or unfastened helmet offers little protection. Wear gloves, boots, a jacket and eye protection. A pillion passenger needs a proper seat and footrests, and the rider must hold the right licence. Keep the number plate, silencer and lights legal and unobstructed.

Worked example

Your chain has 45 mm of slack when the handbook says 25-35 mm, and it looks dry. The correct response is to adjust it to the specified slack at the tightest point, check rear-wheel alignment, lubricate it, and investigate why it loosened. Do not simply tighten it until it feels hard: an over-tight chain can destroy the output-shaft bearing and rear suspension.

Tyre pressure and load

Set pressures cold, then add the pillion or luggage figure from the handbook. Under-inflation makes steering heavy and overheats the tyre; over-inflation reduces the contact patch.

Traps

Checking pressure after a ride; ignoring a spongy brake lever; wearing loose clothing that can snag; carrying a passenger on a machine without pillion footrests; and treating a helmet as a one-size item rather than checking fit and fastening.
