What is an engine seizure caused by? What is an engine seizure caused by?

  • A. Changing down a gear too early

  • B. Changing up a gear too early

  • C. Not enough lubrication in the engine

  • D. Cold weather

    The correct answer is C
    Correct. Engine seizure is caused by a lack of lubrication. Without oil, the engine's moving parts can't move smoothly against each other and the engine will overheat. The strongest signal that an engine is about to seize is that the power drops. There may be a change in the engine tone as well.

Mechanical failure in motorbikes

The types of mechanical failure that would give the largest cause for concern when riding your bike are engine seizure, brake failure, tyre failure and your chain breaking. 

If your chain breaks the engine will rev higher and you will lose power. There's also a risk of the chain locking the back wheel which will cause a skid.

If the brakes fail it could be due to brake fade, which is where the brakes overheat and the pads and brake fluid can't provide braking power any more, or it could be a mechanical reason such as a broken disk.

If you get a puncture or (worse) a blowout, then avoid braking if possible, and let your bike coast to a stop. A blowout on a corner is far more likely to cause you to come off your bike. While you can't always prevent against punctures and blowouts, ensuring that your tyres are kept in good condition is the best way to minimise the risk.

Check out these simple checks you can do on your motorbike to keep it in top condition and reduce the chances it will break down.

It is far more likely to have rider failure than mechanical failure, so look after yourself and improve your skills so that you stay safe on the road.
