💡 What does the warranty cliff mean?
The Yamaha Wr450f actually sees a 31% 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 3 (35.0% 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 Wr450f MOT Data
The Yamaha Wr450f is a niche vehicle in the UK, with 4,612 MOT test results recorded in our database spanning 12 manufacture years. It has an overall MOT pass rate of 77.3% and a failure rate of 22.7%, which is well above the UK average of approximately 37%.
For Yamaha Wr450f 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 steering and suspension 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 Wr450f is likely to perform.
Motorcycle lighting and signalling — 15.1% of failures
Motorcycle lighting and signalling issues account for 15.1% of MOT failures on the Yamaha Wr450f. 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 steering and suspension — 9.1% of failures
Motorcycle steering and suspension issues account for 9.1% of MOT failures on the Yamaha Wr450f. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Motorcycle brakes — 6.6% of failures
Motorcycle brakes issues account for 6.6% of MOT failures on the Yamaha Wr450f. 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).
