What Is Checked in a Motorcycle MOT?
The parts a tester inspects on a motorcycle MOT, from lights and brakes to the frame and exhaust, and what the test does not cover.
The MOT checks that important parts of your motorcycle meet legal standards for safety and the environment. It is not a service and it does not check the bike's general mechanical condition. DVSA guidance lists the main areas below.
Lights
Condition, operation and security of the lights, the colour of the headlamp, the rear lights, indicators and reflectors, and the aim of the headlamp.
Steering and suspension
Condition and security of the forks, handlebars, grips, head bearings, swinging arm and shock absorbers, and whether the damping works properly.
Wheels and tyres
Condition, security, size and type, correct fitting, tread depth and valve condition.
Frame
Cracks, damage, distortion and any corrosion likely to affect the steering or braking.
Brakes
Condition, operation and performance (an efficiency test), and the brake controls.
Exhaust and fuel system
The exhaust must be secure, complete and not too noisy. The fuel system is checked for leaks and for secure components.
Seats, wheel alignment and horn
A rider's seat must be fitted and any seat attached securely. Front and rear wheels must line up. The horn must work and be suitable for the bike.
Sidecars
Where a sidecar is fitted, the tester checks its attachment, alignment, suspension, wheel bearings, wheel alignment, lights and tyre.
Registration plate and identification
The registration plate, vehicle identification number and frame number are checked too.
What the MOT does not check
The condition of the engine, clutch and gearbox is not part of the test. That is why a service still matters even when the bike passes.
Results: dangerous, major, minor and advisory
A bike fails if the tester records any "dangerous" or "major" problem. "Minor" problems and "advisories" do not cause a fail, but they tell you what to watch or fix. You can watch the test from a viewing area, but you cannot interrupt the tester.
A quick check before you go
- All lights, indicators and the brake light work.
- The horn works.
- Tyres have enough tread and no cuts or bulges.
- The chain is adjusted and the brakes work smoothly.
- The number plate is clean, secure and legible.
