About Ktm Sx125 MOT Data
The Ktm Sx125 is a rare vehicle in the UK, with 225 MOT test results recorded in our database spanning 3 manufacture years. It has an overall MOT pass rate of 74.2% and a failure rate of 25.8%, which is above the UK average of approximately 37%.
For Ktm Sx125 owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on motorcycle steering and suspension and motorcycle lighting and signalling 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 Sx125 is likely to perform.
Motorcycle steering and suspension — 24.4% of failures
Motorcycle steering and suspension issues account for 24.4% of MOT failures on the Ktm Sx125. 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 lighting and signalling — 17.8% of failures
Motorcycle lighting and signalling issues account for 17.8% of MOT failures on the Ktm Sx125. 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 — 13.3% of failures
Motorcycle brakes issues account for 13.3% of MOT failures on the Ktm Sx125. 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).
