Honda Cbx750 (1985)
1985 Honda Cbx750
CarHunch analysed 174 real MOT records for the 1985 Honda Cbx750. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1985 Honda CBX750 passes its MOT at 84.8%, meaningfully above the UK average of 80%, and dangerous defects are rare at just 9.8% of vehicles—a solid result for a 40-year-old motorcycle. What makes this cohort particularly reliable is its low failure rate of 0.98 per vehicle, suggesting most issues are minor when they do occur.
These bikes are turning up with modest mileage of around 37,000 miles on average, which is typical for their age and suggests many have been kept for leisure rather than commuted hard. The 3.3 advisories per vehicle point to ageing consumables and cosmetic wear rather than structural problems, so budget for regular maintenance—but if you're buying one, check the service history carefully to understand what's already been done.
What to check before buying a 1985 Honda Cbx750
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.
