Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Wr125r is likely to perform.
Motorcycle brakes — 28.9% of failures
Motorcycle brakes issues account for 28.9% of MOT failures on the Yamaha Wr125r. 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 — 18.0% of failures
Motorcycle lighting and signalling issues account for 18.0% of MOT failures on the Yamaha Wr125r. 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 tyres and wheels — 15.3% of failures
Motorcycle tyres and wheels issues account for 15.3% of MOT failures on the Yamaha Wr125r. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
