💡 What does the warranty cliff mean?
The Yamaha Fz1s actually sees a 3% decrease in failure rate after the warranty period. This is likely due to survivorship bias — unreliable cars are already off the road by this age. Peak failure occurs at age 17 (14.7% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Yamaha Fz1s MOT Data
The Yamaha Fz1s is a relatively common sight on UK roads, with 12,071 MOT test results recorded in our database spanning 8 manufacture years. It has an overall MOT pass rate of 89.6% and a failure rate of 10.4%, which is well above the UK average of approximately 37%.
For Yamaha Fz1s owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on motorcycle lighting and signalling and motorcycle brakes for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Fz1s is likely to perform.
Motorcycle lighting and signalling — 3.9% of failures
Motorcycle lighting and signalling issues account for 3.9% of MOT failures on the Yamaha Fz1s. Motorcycle lighting and signalling 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 — 3.1% of failures
Motorcycle brakes issues account for 3.1% of MOT failures on the Yamaha Fz1s. 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).
Motorcycle lamps and reflectors — 2.9% of failures
Motorcycle lamps and reflectors issues account for 2.9% of MOT failures on the Yamaha Fz1s. 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.
