Yamaha Wr 125 R MOT Reliability Overview
The Yamaha Wr 125 R is a niche vehicle in the UK, with 3,098 MOT test results recorded in our database spanning 5 manufacture years. It has an overall MOT pass rate of 65.7% and a failure rate of 34.3%, which is slightly above the UK average of approximately 37%.
Based on this data, the Yamaha Wr 125 R earns a "Good" reliability rating. The average Yamaha Wr 125 R presents for MOT with approximately 13,775 miles on the clock. Manufacture year matters: 2013 models achieve the highest pass rate at 68.6%, while 2009 models have the lowest at 62.9%. This 5.7 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Yamaha Wr 125 R is Motorcycle brakes, affecting 26.9% of all tests. 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. The second most common issue is Motorcycle lighting and signalling at 18.4%. Motorcycle lamps and reflectors rounds out the top three at 14.8%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?
The Yamaha Wr 125 R 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 6 (36.9% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Wr 125 R is likely to perform.
Motorcycle brakes — 26.9% of failures
Motorcycle brakes issues account for 26.9% of MOT failures on the Yamaha Wr 125 R. 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 lighting and signalling — 18.4% of failures
Motorcycle lighting and signalling issues account for 18.4% of MOT failures on the Yamaha Wr 125 R. 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 lamps and reflectors — 14.8% of failures
Motorcycle lamps and reflectors issues account for 14.8% of MOT failures on the Yamaha Wr 125 R. 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.
