Common Quad Bike MOT Failures and How to Avoid Them

Owning a quad bike brings adventure and utility, whether you’re using it for leisure, farming, or off-road fun. However, to keep your quad bike road legal and safe, passing the quad bike MOT is crucial. Many quad bike owners face unexpected failures during the MOT process, but with a little preparation, you can avoid these issues and keep your quad in top condition.

1. Worn or Damaged Tires

One of the leading reasons for MOT failures is worn-out or damaged tyres. Quad bikes, particularly those used on rugged terrain, experience significant wear. Cracks, bulges, or insufficient tread depth can result in an MOT failure.

How to Avoid It:

• Regularly inspect your quadbike's tyres for signs of wear.
• Replace tyres that show cracks or have less than the legal tread depth of 1.6mm.
• Consider investing in durable off-road tyres if you use your quad bike on rough terrains frequently.

2. Faulty Lights and Indicators

Faulty lighting systems, including headlights, indicators, and brake lights, can easily lead to an MOT failure. For road-legal quad bikes, these components are critical for safety.

How to Avoid It:

• Test all lights before booking your MOT.
• Replace burnt-out bulbs or fix wiring issues promptly.
• Ensure indicators flash correctly and brake lights activate when the brakes are applied.

3. Braking System Problems

A reliable braking system is vital for both off-road and road-legal quad bikes. Faulty brakes or uneven braking pressure can not only fail the MOT but also pose serious safety risks.

How to Avoid It:

• Schedule regular quad bike servicing near you to inspect and maintain the brakes.
• Address issues like squeaking sounds, reduced braking power, or spongy brake pedals immediately.
• Use high-quality brake pads and fluid to keep your braking system in top shape.

4. Steering and Suspension Issues

Faulty steering or suspension can compromise the safety and performance of your quad bike. During an MOT, these components are thoroughly tested, and any instability or excessive play will result in failure.

How to Avoid It:

• Check for signs of wear or looseness in the handlebars or suspension.
• Keep your steering mechanism well-lubricated and aligned.
• Opt for a quad bike service near you to address these issues before your MOT.

5. Exhaust Emissions and Noise Levels

For road-legal quad bikes, emissions and noise levels must meet legal standards. A noisy or leaking exhaust system can lead to an MOT failure.

How to Avoid It:

• Inspect the exhaust for leaks or cracks and repair them promptly.
• Service your engine to ensure it’s running efficiently and within emission limits.
• For petrol quadbikes, use high-quality fuel and keep your exhaust system clean.

The Importance of Regular Servicing

Regular servicing is your best defence against unexpected MOT failures. By scheduling routine maintenance with a trusted service provider, you can identify and fix potential problems before they escalate. Whether you need quad bike repairs near you, a dirt bike service, or a pre-MOT inspection, staying proactive will save you time and money in the long run.
