2003 Honda Cg125

CarHunch analysed 231 real MOT records for the 2003 Honda Cg125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2003 Honda CG125 passes its MOT first time in just 68.2% of cases, well below the UK average of 80%, which means you're facing a notably higher chance of a failed test and costly repairs. With 14.3% of these bikes having suffered a dangerous defect at some point, structural or safety issues aren't rare enough to ignore when evaluating an older example.

These machines are typically light on miles for their age—median of 18,662—but they still rack up an average of 1.66 failures and 4.2 advisories per test, pointing to cumulative wear rather than sudden catastrophic faults. Before buying, budget for a pre-purchase inspection by a specialist mechanic and factor in that a proportion will need work to pass their next MOT.

What to check before buying a 2003 Honda Cg125

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.
