Manufacture year matters: 2018 models achieve the highest pass rate at 91.2%, while 2005 models have the lowest at 60.5%. This 30.7 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Ktm 450 is Motorcycle lamps and reflectors, affecting 13.1% 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 suspension at 5.7%. Motorcycle brakes rounds out the top three at 4.4%. 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 450 ages relatively gracefully. The failure rate increase of 2% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 4 (21.1% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Ktm 450 MOT Data
The Ktm 450 is a niche vehicle in the UK, with 2,315 MOT test results recorded in our database spanning 17 manufacture years. It has an overall MOT pass rate of 81.7% and a failure rate of 18.3%, which is well above the UK average of approximately 37%.
For Ktm 450 owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on motorcycle lamps and reflectors and motorcycle 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 450 is likely to perform.
Motorcycle lamps and reflectors — 13.1% of failures
Motorcycle lamps and reflectors issues account for 13.1% of MOT failures on the Ktm 450. 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 suspension — 5.7% of failures
Motorcycle suspension issues account for 5.7% of MOT failures on the Ktm 450. 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 — 4.4% of failures
Motorcycle brakes issues account for 4.4% of MOT failures on the Ktm 450. 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).
