Motorcycle MOT (Cost, Checklist and Requirements)


Is your motorcycle safe and legal?

To legally ride your motorcycle on UK roads, you must have a valid MOT test certificate confirming that your bike has undergone several mechanical safety checks.

Primarily, these involve brakes, lights and steering mechanisms, but the checklist has vastly expanded since 1960 when testing first began.

That list may constitute a minefield of defects, faults and problems, any one of which can result in your motorbike failing its MOT test.

Do you know what’s on that list?

What, where and when?

The Ministry of Transport (MOT) no longer exists; vehicle testing is now authorized via the Department of Transport, but the age-old test name of MOT, remains.

Quite simply, the MOT is a test… an inspection of your motorcycle once it is more than three years old.

After that, the MOT test is required yearly to ensure that your bike is safe, roadworthy and legal.

Only authorized garages or test centres may conduct an MOT test on cars or motorcycles.

What does a motorcycle MOT cost?

The price of an MOT for any motorcycle is £29.65.

Bikes with a sidecar pay £37.80.

That compares favourably with a saloon car priced at £54.85.

MOT Checklist

You can improve your bike’s chances of passing an MOT with advance knowledge of what the garage will test it for.

Cleaning, polishing and putting air in the tires are all very nice, but an authorized MOT testing facility has a long list of mechanical and electrical inspections to carry out.

A bike sitting in a shed for months on end poses no risk to others, but out on the road, any weak points can lead to serious injury or death to both riders and others.

Here’s your checklist in more detail; check all these areas before heading to the testing station. 

Lights and Signaling: Motorcycle lights are to see and be seen. MOT testing ensures they’re securely attached, in good condition, and work correctly.

Your indicators, rear lights and reflectors should be fully functional.

The headlight’s aim must be set correctly to avoid dazzling drivers ahead or casting an unsafe short-distance beam.

Steering and Suspension: The condition of the steering and suspension is inspected to assess whether the forks, handlebars, grips mountings, head bearings, swinging arm, shock absorbers and damping effect are secure and properly working.

Pay particular attention to the fork seals. If there’s excessive oil leaking, your bike will fail. Try grabbing the handlebars, squeezing the front brake lever and pushing the bike forward to check the damping action.

Check the rear wheel damping action also for any free play or looseness.

Wheels and Tyres: In poor condition, wheels and tyres are a source of risk. Are yours the wrong size, poorly fitted or with worn tread? Take a look.

It’s a good idea before the test to check for loose spokes and any distortions.

Current UK regulations require 1mm of tread across 3/4 of the tyre. Are the front and rear tyres compatible and suitable for road use?

Inflate the tyre pressures to their correct pressure, or they may affect the outcome of the brake test.

Frame and Structure: During the MOT, the frame of your bike is checked for cracks, damage, distortion and corrosion, which could have an adverse effect on steering and braking.

Brakes: The ability of a rider to safely control their motorcycle’s braking system requires a separate efficiency test assessing the brakes’ performance, condition and controls.

The best you can do on a pre-check is to spin the wheel and press the brake lever. It should grind to a halt. Ride the bike, too and test the brakes by stopping.

During a test, the bike is placed on a roller device that produces a computerized readout.

Exhaust System: Is your exhaust system secure and quiet? Some exhaust systems are louder than others, such as those on certain Harley Davidson models.

It will probably pass as long as the noise is intentional and not ear-shattering. It will fail if the excessive noise source is attributable to a leaking or broken exhaust pipe. Read more about motorcycle exhaust laws in the UK.

Other Inspection Areas

  • The fuel system will be checked for leaks, and its components are secure. Leaking fuel may cause a fire or explosion.
  • Is the seat properly attached and secured?
  • Horn: working and suitable for the vehicle? If you’ve fitted a ship’s claxon, it’s probably time to tone it down a little!
  • Chains and guards, along with the sprockets, are checked for wear and tension. A chain slipping or locking up on damaged sprockets may lead to an out-of-control motorcycle.
  • The throttle cable and clutch lever are checked to see if they’re working properly. The clutch lever shouldn’t be bent, damaged or shortened.
  • Footrests are inspected to check that they’re present and firmly attached. Look out for any obstructions, looseness or damage.
  • Less mechanical areas that are checked include the license plates, vehicle identification and frame number. Are they in order, visible and undamaged?

Why do motorcycles fail their MOT tests?

The reasons vary, but ignorance is a key factor. Why not give your bike a ‘trial run’ before putting it through its MOT? At the very least, you can visit the government website for the MOT motorcycle inspection list.

This avoids making silly mistakes like having your bike fail over a minor fault such as a broken light bulb.

According to government-produced MOT test statistics, 18.2% of motorcycles failed their initial tests from 2015 to 2016.

Lighting and indicators, brakes, steering and tyres were the main culprits, so check these carefully before putting your bike in for an MOT.


What happens if you fail a motorcycle MOT test?

Hopefully, you won’t, but you’ll have ten days to fix any problems and take a free re-test. After that, you pay the full price for a new test.

If the vehicle is grounded on serious issues such as corrosion or structural damage, it will fail outright, and no short-term re-test is possible. In such cases, you’ll need to fix the problem and take a new test.

One could argue that test garages might be tempted to overstate the faults to benefit from corrective work.

It would be unfair to label all garages this way, and it’s down to the rider and the garage to thoroughly discuss the testing procedures and condition of the bike beforehand.

Try to build a good long-term relationship with a reputable garage with which you’re comfortable.

Even if you have very little mechanical expertise, a simple visual inspection of the listed items allows you to identify problems and arrange to have your bike fixed by a mechanic before the inspection.

Exempt motorcycles

Certain motorcycles are exempt from the MOT test if they fall into two categories:

1. Very new motorcycles.

2. Very old motorcycles.

Motorcycles less than three years old do not require an MOT. Once they are three years old, they must take an annual MOT test.

Motorcycles and cars built before 1960 are somewhat controversially exempt from an MOT test.

The 2012 rule change came about mainly through East Yorkshire MP George Knight, who campaigned on behalf of the All Party Parliamentary Historic Vehicles Group.

He argued that classic vehicles did not have ABS brakes and catalytic converters. They were also unlikely to be driven much on public roads.

The spirit of the MOT test is, of course, centred on the safety of riders and others and with that in mind, owners are still legally responsible for ensuring that their bikes and cars are safe and roadworthy. They are also still free to take an MOT if they wish.

An exemption is not an excuse to drop standards. Using an unsafe motorcycle on public roads remains illegal and dangerous.


Why not make yourself a cup of coffee, put your bike up on its stand somewhere quiet and check all the items on the MOT inspection list?

You will hopefully catch minor faults… any of which could result in a failure.

If your current MOT certificate has expired, you’re legally permitted to ride it to the test centre for a new MOT, provided you have a pre-arranged appointment. You’re also allowed to ride it to a garage for repairs but avoid any multi-day, 1,000-mile detours!

A lot can happen in a year. Don’t let complacency creep in once your bike has passed its MOT test. Regular maintenance and pre-ride checks will catch new or developing problems.

A motorcycle remains safe, valuable and a pleasure to ride when in sound and reliable mechanical condition.

Safe and happy riding to all.
