1986 Honda Nh 80 Md G

CarHunch analysed 321 real MOT records for the 1986 Honda Nh 80 Md G. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1986 Honda NH 80 MD-G has a first-time MOT pass rate of just 1.5%, catastrophically below the UK average of 80%—making it one of the least reliable vehicles in its age cohort. The good news is that dangerous defects are absent entirely (0%), and when failures do occur they're extremely rare (0.01 per vehicle on average), suggesting the issues are minor rather than safety-critical.

These are genuinely ancient machines with very low mileage for their age (median 3,781 miles), which explains why so few pass their first attempt: they've likely been stored or used minimally, causing rubber seals, fuel systems, and electrical components to deteriorate. Before committing to one, budget for a pre-purchase inspection focused on fuel delivery, electrics, and brake fluid condition—these are the typical culprits on long-dormant bikes, not structural faults.

What to check before buying a 1986 Honda Nh 80 Md G

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.
