💡 What does the warranty cliff mean?
The Harley-davidson 1200 ages relatively gracefully. The failure rate increase of 9% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 12 (18.3% 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 1200 is likely to perform.
Motorcycle lamps and reflectors — 5.5% of failures
Motorcycle lamps and reflectors issues account for 5.5% of MOT failures on the Harley-davidson 1200. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Motorcycle lighting and signalling — 4.9% of failures
Motorcycle lighting and signalling issues account for 4.9% of MOT failures on the Harley-davidson 1200. 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 brakes — 3.9% of failures
Motorcycle brakes issues account for 3.9% of MOT failures on the Harley-davidson 1200. 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).
