💡 What does the warranty cliff mean?
The Honda Cg125 ages relatively gracefully. The failure rate increase of 15% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 13 (32.3% 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 Cg125 is likely to perform.
Motorcycle lighting and signalling — 18.8% of failures
Motorcycle lighting and signalling issues account for 18.8% of MOT failures on the Honda Cg125. 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 steering and suspension — 12.8% of failures
Motorcycle steering and suspension issues account for 12.8% of MOT failures on the Honda Cg125. 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 brakes — 11.2% of failures
Motorcycle brakes issues account for 11.2% of MOT failures on the Honda Cg125. 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).
