Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Yz250 is likely to perform.
Motorcycle steering and suspension — 9.8% of failures
Motorcycle steering and suspension issues account for 9.8% of MOT failures on the Yamaha Yz250. 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 tyres and wheels — 8.9% of failures
Motorcycle tyres and wheels issues account for 8.9% of MOT failures on the Yamaha Yz250. 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.
Motorcycle lighting and signalling — 8.6% of failures
Motorcycle lighting and signalling issues account for 8.6% of MOT failures on the Yamaha Yz250. 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.
