Should I check the MOT history before buying a 1984 Yamaha Fj1100?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

The 1984 Yamaha FJ1100 passes its MOT first time in 82% of cases, slightly above the UK average of 80%, suggesting reasonable baseline reliability for a 40-year-old machine. The dangerous defect rate of 8.7% is comfortably low, so structural and safety failures are not a widespread concern with this model.

These bikes are running at genuinely modest mileage for their age—averaging around 41,000 miles—which explains the decent pass rate and suggests many have been well-maintained garage queens rather than hard-used commuters. Expect roughly one failure and three advisories per test, typically minor wear items like suspension and lighting rather than engine problems. Before buying, get the service history and have a pre-purchase inspection focus on brake condition and fuel system integrity, as these are common weak points on machines this old.
