What Fails Most
Best Year to Buy
Based on MOT data, 2018 models have the highest pass rate at 93.8%.
Based on 2024 MOT test results only — the most recent data available. "Built" = year of manufacture. Cars need their first MOT at 3 years old, so the newest cars shown are from ~3 years ago.

💡 What does the warranty cliff mean?
The Yamaha Mt ages relatively gracefully. The failure rate increase of 5% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 9 (15.9% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.
* High Fail Rate badge indicates an MOT pass rate below 65% (failure rate above 35%).

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Mt is likely to perform.
Motorcycle lamps and reflectors — 10.0% of failures
Motorcycle lamps and reflectors issues account for 10.0% of MOT failures on the Yamaha Mt. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Motorcycle structure and attachments — 7.0% of failures
Motorcycle structure and attachments issues account for 7.0% of MOT failures on the Yamaha Mt. Motorcycle structure and attachments issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
Motorcycle brakes — 6.2% of failures
Motorcycle brakes issues account for 6.2% of MOT failures on the Yamaha Mt. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
