Should I check the MOT history before buying a 1981 Yamaha Xs650?

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.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 1981 Yamaha XS650 passes its MOT first time at 86.6%, which is a solid 6.6 percentage points above the UK average of 80%, suggesting these bikes are generally well-maintained by their owners. The dangerous defect rate sits at a low 5.7%, so serious safety issues are uncommon in this cohort.

At a median mileage of just over 16,000 miles, these machines are clearly cherished classics rather than daily runners, which explains the relatively reliable test results. With an average of 0.8 failures and 2.2 advisories per vehicle, you're looking at straightforward wear items rather than systemic problems—but have any prospective purchase inspected for corrosion and electrical gremlins, as those tend to catch older bikes out.
