2005 Honda Cbr 125 RS 5

CarHunch analysed 283 real MOT records for the 2005 Honda Cbr 125 RS 5. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2005 Honda CBR 125 RS-5 is a reliability concern: just 58.2% of these bikes pass MOT first time, well below the UK average of 80%, and a quarter of all examples (25.1%) have recorded dangerous defects at some point. That's a genuine buyer red flag, particularly for a learner-friendly 125cc model where you'd expect better durability.

These bikes are running low mileage for their age—averaging 14,373 miles—yet still racking up 1.83 failures and 6.9 advisories per vehicle, suggesting wear and corrosion issues rather than hard use. Before committing to one, have a pre-purchase inspection focus on the fuel system and electrics, where cheap fixes often hide bigger problems on older small-capacity bikes.

What to check before buying a 2005 Honda Cbr 125 RS 5

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.
  • ⚠️ 25.1% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
