If you ride a motorcycle, preparing for your MOT test isn’t just about booking a date and turning up. Taking some time beforehand to carry out basic maintenance checks can make the difference between passing first time and facing costly and inconvenient re‑tests.

This guide outlines practical and easy‑to‑follow tips for motorcyclists to prepare their bikes for an MOT. Whether you ride every day or only in the summer months, these checks will help ensure your motorcycle is safe, roadworthy and ready for its inspection.

Why Pre‑MOT Maintenance Matters

An MOT test is designed to check that your motorcycle meets the UK’s minimum safety and environmental standards. While the test itself is thorough, there are many common reasons why bikes fail that can easily be avoided with a little preparation.

Doing your own checks before your MOT not only increases the likelihood of passing but also improves your safety and confidence on the road. It can also uncover issues early, saving you money in the long run.

Check Your MOT Status

Before booking your test, it’s a good idea to check your MOT due date or look through the test history. You can do this quickly using the official GOV.UK MOT history checker.

Check Your Lights and Signals

One of the most common MOT failures across all vehicle types involves lighting. On a motorcycle, this includes:

• Headlight (both dipped and main beam)
• Tail light
• Brake light
• Indicators
• Number plate light (if fitted)

Make sure every light works correctly and that lenses are clean and free from cracks. Replace any blown bulbs and tighten loose fittings. If your bike has aftermarket lighting, ensure it meets legal standards.

Inspect Tyres Carefully

Tyres are another frequent cause of MOT failure. Before your test:

• Check the tyre tread depth. The legal minimum is 1mm across the central three‑quarters of the tread. Motorcycles with an engine capacity not greater than 50cc do not need to have 1mm of tread. They must have a visible tread pattern around the entire circumference and across the whole breadth of the tread.
• Look for cuts, bulges, or uneven wear.
• Ensure the tyres are correctly inflated to the manufacturer’s recommended pressures.

Use the pressure figures from your owner’s manual or the markings on the bike itself. Incorrect pressures affect handling and can lead to premature wear.

Brake System and Performance

Brakes are critical for rider safety and a common reason for MOT failure.

Start by inspecting:

• Brake pads and discs for wear.
• Hydraulic lines for visible damage or leakage.
• Cable‑operated brakes for smooth movement and no fraying.

During a short test ride, check that the front and rear brakes operate smoothly without noise, juddering or excessive lever travel. If you notice any issues, it’s often best to have them checked professionally before the MOT.

Chain, Sprockets and Drive System

The drive system is unique to motorcycles and needs proper attention. Before your MOT:

• Clean and lubricate the chain.
• Check for correct chain tension according to the manufacturer’s specification.
• Inspect sprockets for wear or hooked teeth.

A worn chain or sprocket set not only fails part of the MOT visual inspection, but it also affects performance and can increase the risk of breakdown.

Frame, Suspension and Steering

Structural components are assessed carefully during the MOT. Check for:

• Any visible cracks, corrosion or damage to the frame.
• Smooth, even movement in the forks and rear suspension.
• No unusual play or stiffness in the steering head.

Feel for any looseness or unusual noises when you move the handlebars from side to side. If steering or suspension feels inconsistent, it’s worth having a professional take a look.

Horn and Mirrors

Simple items like the horn and mirrors are easy to overlook but are essential parts of the MOT.

Make sure:

• The horn works and is loud enough to be heard over typical traffic noise.
• Mirrors are securely attached and give a clear view of the road behind.

Loose or missing mirrors and a faulty horn are both common causes of MOT failure.

Mirrors should be clean, secure and give a clear view. It’s also a good time to remind yourself of your legal responsibilities as a rider, especially those covered in The Highway Code’s section for motorcyclists.

Fuel, Fluids and Leaks

Inspect your motorcycle for any fluid leaks. Common areas include:

• Brake fluid reservoir
• Fork seals
• Engine and gearbox areas

Also check fluid levels and top up where recommended:

• Brake fluid
• Engine oil
• Coolant (for liquid‑cooled bikes)
• Fork oil if service history suggests it is due

Leaks are a frequent reason bikes fail their MOT, so thoroughly check the underside and chassis before booking your test.

Exhaust and Emissions Readiness

Your bike’s exhaust system must be secure and free from excessive corrosion or holes. During the MOT, the tester will also evaluate emissions, so:

• Ensure there are no leaks in the exhaust.
• Replace damaged mufflers or exhaust parts as needed.

Aftermarket exhausts should be road legal and not overly loud, as this can affect emissions testing and may be flagged in the MOT.

Windscreen and Bodywork

If your motorcycle has a screen, fairing or additional bodywork:

• Check for cracks or sharp edges.
• Ensure fittings are secure.

Any loose components can fail an MOT visual inspection.

Documents and Practical Preparation

Before your MOT appointment:

• Take your motorcycle’s V5C (logbook) and previous MOT certificates.
• Make sure your registration details are correct.
• Arrive with your bike clean and accessible for inspection.

A clean bike helps testers see components clearly and gives a better first impression.

When to Get Professional Help

While many of the checks above can be done at home, some issues are best handled by an experienced mechanic. If you discover:

• Brake problems
• Suspension issues
• Persistent oil leaks
• Significant tyre wear

Booking in a professional inspection with a trusted local garage, such as Adderley Green Garage can save time and ensure your motorcycle is fully prepared for its MOT.
