For Yamaha Yz426f 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 Yz426f is likely to perform.
Motorcycle steering and suspension — 19.5% of failures
Motorcycle steering and suspension issues account for 19.5% of MOT failures on the Yamaha Yz426f. 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 — 16.9% of failures
Motorcycle lighting and signalling issues account for 16.9% of MOT failures on the Yamaha Yz426f. 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 — 10.4% of failures
Motorcycle tyres and wheels issues account for 10.4% of MOT failures on the Yamaha Yz426f. 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.
