What is a motorbike MOT?

The MOT test is an annual check that ensures motorcycles over three years old are safe and roadworthy and meet environmental standards.

You’ll need to take your motorbike to an approved MOT test centre and once passed, you'll receive an MOT certificate, which is your ticket to legally ride on UK roads.

Does my motorbike need an MOT?

Yes, riding without a valid MOT certificate isn't just a minor oversight - it's illegal and can hit your wallet with a fine of up to £1,000.

The exceptions to this rule are:

• If you're en route to a pre-scheduled MOT test

• Your motorbike is more than 40 years old and you haven’t made any major changes in the past 30 years. However, you still need to make sure your classic motorcycle is still in good condition

Without a valid MOT:

• Your insurance might not be valid, or it may only extend to third-party cover, leaving you exposed to significant financial risks in the event of an accident

• You'll be unable to legally tax your motorcycle, which is another requirement for riding on public roads

• Parking your motorcycle on the road becomes an illegal act, potentially leading to more fines and headaches

How does a motorbike MOT test work?

When your motorcycle undergoes an MOT test, it's subjected to a grading system that classifies defects into five categories: Dangerous, Major, Minor, Advisory, or Pass.

The classification is based on how each defect impacts safety and the environment. It's a thorough process designed to ensure that every motorcycle on the road is not only safe for the rider but also for everyone else sharing the road.
