💡 What does the warranty cliff mean?
The Suzuki An 400 K7 sees a significant jump in MOT failures after the warranty period. Failure rate increases by 61% once warranty cover ends. Budget for increased maintenance costs from year 4 onwards. Peak failure occurs at age 7 (23.5% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific An 400 K7 is likely to perform.
Motorcycle brakes — 15.5% of failures
Motorcycle brakes issues account for 15.5% of MOT failures on the Suzuki An 400 K7. 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 steering and suspension — 5.3% of failures
Motorcycle steering and suspension issues account for 5.3% of MOT failures on the Suzuki An 400 K7. 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 — 4.5% of failures
Motorcycle tyres and wheels issues account for 4.5% of MOT failures on the Suzuki An 400 K7. 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.
