1984 Honda Cg 125 E
CarHunch analysed 147 real MOT records for the 1984 Honda Cg 125 E. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1984 Honda CG 125 E is fundamentally unreliable by modern MOT standards, with a first-time pass rate of just 4.5% against the UK average of 80%—meaning 95 out of every 100 fail their test. The good news is that dangerous defects are rare at 0.7%, so when these bikes do fail, it's usually fixable rather than unsafe.
At 26,000 miles median mileage for a 40-year-old machine, these are well-used survivors, yet they rack up almost no failures per vehicle (0.07) and minimal advisories (0.1), suggesting the MOT failures are concentrated in just a few problem areas rather than widespread decay. Before buying, get a pre-purchase inspection focused on the specific weak points these bikes are known for—likely emissions or structural corrosion—rather than assuming the bike is a basket case.
What to check before buying a 1984 Honda Cg 125 E
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.
