Based on this data, the Ktm 125 earns a "Very Good" reliability rating. The average Ktm 125 presents for MOT with approximately 11,460 miles on the clock. Manufacture year matters: 2007 models achieve the highest pass rate at 82.9%, while 2003 models have the lowest at 65.3%. This 17.6 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Ktm 125 is Motorcycle lamps and reflectors, affecting 20.3% of all tests. 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. The second most common issue is Motorcycle brakes at 17.0%. Motorcycle structure and attachments rounds out the top three at 16.6%. 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 Ktm 125 shows a relatively stable failure rate after warranty — the change of 2% is negligible. Peak failure occurs at age 10 (35.5% 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 125 is likely to perform.
Motorcycle lamps and reflectors — 20.3% of failures
Motorcycle lamps and reflectors issues account for 20.3% of MOT failures on the Ktm 125. 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 brakes — 17.0% of failures
Motorcycle brakes issues account for 17.0% of MOT failures on the Ktm 125. 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 structure and attachments — 16.6% of failures
Motorcycle structure and attachments issues account for 16.6% of MOT failures on the Ktm 125. 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.
