Honda C90mg (1992)
1992 Honda C90mg
CarHunch analysed 307 real MOT records for the 1992 Honda C90mg. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1992 Honda C90MG has a 4.9% first-time pass rate—catastrophically below the 80% UK average—meaning nearly 95% of these bikes fail their MOT on the first attempt. The petrol versions (303 of the 307 analyzed) perform identically poorly at 3.7%, so fuel type makes no difference here; the issue is systemic to the model and age.
These are genuinely ancient machines with a median mileage of just 26,068 miles, suggesting most have been lightly used or stored for long periods—exactly the conditions that cause mechanical decay in 30-year-old motorcycles. With virtually no dangerous defects recorded and almost no advisories, the failures are likely routine wear items (tyres, brakes, lights, exhaust) rather than hidden structural problems, but if you're considering one, budget for a complete pre-purchase inspection and expect to spend on brake lines, seals, and fuel system cleaning before it passes.
What to check before buying a 1992 Honda C90mg
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.
