122 real MOT outcomes analysed • 83% first-time pass rate

1980 Honda Cb650

CarHunch analysed 122 real MOT records for the 1980 Honda Cb650. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1980 Honda CB650 passes its MOT at 83%, a solid three points above the UK average, with only 7.4% of vehicles ever showing a dangerous defect—well below the concern threshold. This is a genuinely reliable motorcycle for its age.

With a median mileage of just 34,685 miles for a 44-year-old bike, these are low-use examples, which explains the strong pass rate and modest 0.87 average failures per test. Most issues that do emerge are minor advisories (2.3 per vehicle) rather than failures—typical wear items on aging machines. If you're considering one, request its full service history and have a pre-purchase inspection focus on fuel system condition and ignition electrics, as these are common weak points on carburetted machines of this era.

What to check before buying a 1980 Honda Cb650

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
