Motorcycle MOT Preparation Checklist: Pass First Time (2026 UK Guide)

In the UK, every motorcycle and scooter over 3 years old needs an annual MOT test (Ministry of Transport test). Around 40% of motorcycle MOT failures are for items you could have spotted yourself in half an hour — saving the £29.65 re-test fee and a wasted trip to the testing station.

This is the complete pre-MOT checklist covering every test point in the DVSA's motorcycle inspection manual, in the order a tester actually works through them. Run through this the day before your MOT and you'll pass first time.

What gets tested in an MOT

The motorcycle MOT covers 9 categories: lights, steering, suspension, brakes, tyres and wheels, structure and bodywork, fuel system and emissions, the drive system, and seat and footrests. The tester checks each — anything outside spec is either a "minor" (advisory, pass with note) or a "major"/"dangerous" (fail).

1. Lights — the #1 fail reason

Roughly 20% of all motorcycle MOT failures are lighting issues. Check all of these with the bike on its stand and engine off (battery only):

• Headlight — both high and low beam working. Beam aim correct (about 60cm drop over 10m on a wall). Lens not cracked or heavily clouded.
• Tail light — on with the ignition.
• Brake light — operated by BOTH front and rear brake. This is a common fail — front brake light switch sticks on older bikes.
• Indicators — all four, flashing at the correct rate (60–120 per minute). Front and rear.
• Number plate light — easy to forget. Must illuminate the plate.
• Reflectors — rear red reflector required, must be present and not cracked.

Quick fix tip: Carry spare bulbs to the test. The MOT regulations let the tester re-test the same day at no extra cost if you fix a simple item like a bulb on the spot.

2. Tyres and wheels

• Tread depth: minimum 1mm across 3/4 of the breadth, around the whole circumference. Most tyres have wear indicators in the grooves — when they're flush, you're at minimum.
• Tyre damage: no cuts deeper than 25mm or 10% of section width; no lumps, bulges, or cord visible; no plugs in the sidewall (plugs in the tread are permitted).
• Tyre type compatibility: both tyres must be of compatible construction (cross-ply with cross-ply, radial with radial — exceptions exist for specific manufacturer approvals).
• Tyre age: not officially tested but a tester will advise on tyres over 10 years old.
• Wheel condition: no cracks, no obvious bent/buckled rim, no missing spokes (on spoked wheels). Wheel bearings: rock the wheel side-to-side with the bike on a stand — should feel solid, not loose.

3. Brakes

• Brake pad / shoe wear: minimum 1.5mm of friction material on pads. Look through the calliper — if the pad backing plate is visible, replace.
• Brake disc wear: minimum thickness is stamped on the disc itself (typically 4.0–4.5mm for sportbike fronts, 5mm+ for cruiser). Below that = fail. Also check for cracks radiating from the holes.
• Brake fluid level: at or above MIN. Old, dark fluid is an advisory, not a fail — but it should be replaced every 2 years.
• Brake feel: lever shouldn't pull to the bar; pedal shouldn't sink under sustained pressure. Either = spongy = bleed required.
• ABS: on bikes equipped with ABS, the warning light must work — comes on with ignition, goes off after a few seconds or once moving. Permanently on = fail.

4. Steering and suspension

• Steering head bearings: with the front wheel off the ground, turn the bars lock to lock. Should be smooth. A "notch" at dead-centre = worn bearings = fail.
• Fork seals: no oil leaks. A small amount of oil residue is normal; active dripping or wet fork legs = fail.
• Fork operation: press down hard on the bars. Should return smoothly, no clunking, no excessive bounce.
• Rear suspension: press down on the seat. Should return smoothly. Look for oil leaks at the shock(s).
• Swingarm: rock side-to-side at the rear wheel. Excessive movement = worn swingarm bearings = fail.
• Wheel alignment: chain adjusters should match left-to-right (use the alignment marks on the swingarm).

5. Frame, body and footrests

• Frame: no cracks, no obvious corrosion compromising structural integrity, no unauthorized welding or modification.
• Footrests: both rider footrests must be present and secure. Pillion footrests required if pillion seat is fitted.
• Handlebars: secure, no cracks. Bar-end weights are not required but loose bar ends are an advisory.
• Mirrors: at least one mirror, providing a clear rearward view. Cracked or missing = fail. Most testers want two.
• Side stand / centre stand: functional, returns to position under spring tension. Side-stand cut-off switch must work if fitted (engine should die if you put it in gear with the stand down).

6. Exhaust and emissions

• Exhaust security: no excessive corrosion, no holes, no blowing, no loose mounts.
• Noise: the tester listens; obvious loud exhausts get a fail. An aftermarket can with the BSAU 193 marking is fine; an open or de-baffled exhaust is not.
• Visible smoke: bikes registered after 1 March 2007 must not emit visible smoke at any time during the test.
• Catalytic converter: must be present on bikes registered after 1 July 1999. Missing or hollowed-out = fail.

7. Fuel system

• No fuel leaks anywhere. Check around the carb/throttle body, fuel pump, fuel filter, and tank.
• Fuel cap seals properly. A missing or broken cap = fail.

8. Electrical (beyond lights)

• Horn: works, single continuous note (no air horns or musical horns).
• Speedometer: must be present and functional. A non-working speedo is an automatic fail.
• Wiring: no exposed bare wires, no obvious damage, no signs of recent overheating.

9. Seat, registration plate, VIN

• Seat secure — bolted, no signs of loose mounts.
• Rear registration plate — present, securely mounted, correct font and spacing (the new "1234 AB 12" format or earlier). Italic, 3D and tinted plates fail on bikes registered after September 2021.
• VIN visible — must be readable, not obscured or painted over.

Top 10 motorcycle MOT failure reasons (DVSA data)

1. Headlight aim incorrect
2. Tyre tread below minimum
3. Brake light not working (especially front-brake-operated)
4. Steering head bearing wear / notchy steering
5. Brake pad/disc wear below limits
6. Indicator bulb blown or wrong flash rate
7. Fork seal leaking
8. Number plate non-compliant (font, format, lighting)
9. Visible smoke from exhaust
10. Chain dangerously slack or rusted

Run through this list specifically the day before your MOT and you eliminate the vast majority of common failures.

What you'll need at the test station

• The bike (with at least 1/4 tank of fuel — the tester needs to start it)
• Payment (£29.65 maximum fee for a motorcycle, £14.65 for a scooter ≤200cc as of 2026)
• Your V5C is NOT required — only your registration number

You can book MOTs up to 1 month before the expiry date and keep the original expiry date — there's no benefit to leaving it to the last day.

FAQ

Can I ride my bike to the MOT if it's expired?

Yes — you can ride to a pre-booked MOT appointment on an expired MOT, provided the bike is otherwise roadworthy and insured. Riding without an appointment = uninsured/illegal.

What's the difference between an advisory and a fail?

Advisory ("Minor") = pass, but the tester flags an item that will need attention soon (e.g. tyres at 1.5mm). Major or Dangerous = fail. Dangerous items can't be ridden away — you need to fix them or trailer the bike.

How long is a free re-test?

If you leave the bike at the testing station and they fix the failed item the same day, no re-test fee. If you take it away and bring it back within 10 working days, partial re-test only, often free or reduced.

Do classic motorcycles need an MOT?

Bikes manufactured before 1 January 1960 are MOT-exempt. Bikes 40+ years old that haven't been "substantially modified" may also qualify for exemption — you self-declare on the V5C.

Is an MOT proof of roadworthiness?

It's a snapshot — the bike was roadworthy at the moment of test. It's your legal responsibility to keep it that way.
