How to Pass Your Motorcycle MOT – Common Reasons Bikes Fail
Motorcycle MOT
A failed MOT is frustrating — especially when it’s something that could have been sorted beforehand.
Most failures come down to a few common issues that riders either overlook or don’t realise are a problem.
Here’s what to check before your motorcycle MOT and how to avoid an unnecessary fail.
🔧 1. Worn Tyres
Tyres are one of the most common reasons for failure.
Check for:
- low tread depth
- cracks or damage
- uneven wear
👉 If in doubt, get them looked at before your MOT.
🔧 2. Brake Issues
Brakes need to be in proper working condition.
Common problems:
- worn brake pads
- weak braking response
- fluid issues
👉 This is a quick fix if caught early.
🔧 3. Lights Not Working
Simple but often missed.
Check:
- headlights (high and low beam)
- indicators
- brake lights
👉 A blown bulb alone can cause a fail.
🔧 4. Chain & Drive Condition
A loose or poorly maintained chain can lead to failure.
Look for:
- excessive slack
- rust
- lack of lubrication
🔧 5. Exhaust Problems
Your exhaust must:
- be secure
- not excessively loud
- not leaking
Aftermarket systems can sometimes cause issues if not fitted properly.
🔧 6. General Condition
Testers will also look at:
- overall safety
- structural condition
- anything obviously unsafe
