MOT rules for motorcycles in the UK

When an MOT is due

Motorcycles in the UK need an MOT test once the bike is over three years old, then annually. You can check the due date and MOT history of any bike for free on the government's MOT service at gov.uk — worth doing on any used purchase, and worth doing on your own bike so the expiry never surprises you. Vehicles over 40 years old can be registered as a vehicle of historic interest and exempt from the test, as long as they haven't been substantially changed — the declaration is made when taxing the vehicle.

What the test covers on a motorcycle

• Wheels and tyres — condition, tread, and compatibility.
• Brakes — performance and controls, front and rear.
• Steering and suspension — including head bearings and fork seals.
• Frame — condition and any dangerous modification or corrosion.
• Lights, reflectors and horn.
• Exhaust system and noise.
• Wheel bearings and drive components for security and wear.

If it fails

You get a failure document listing each defect and whether it's dangerous (bike can't be ridden on the road until repaired) or major (must be repaired to pass). Minor defects are noted but don't fail the test. You can have the bike repaired and retested — a partial retest applies if you return it to the same test centre within a set window. Your directory listing's workshop or any MOT station can quote the repairs; itemise them the same way you would a service.
