2001 Kawasaki Kmx125 B11

CarHunch analysed 173 real MOT records for the 2001 Kawasaki Kmx125 B11. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2001 Kawasaki KMX125-B is a serious reliability red flag, with a first-time MOT pass rate of just 8.4%—a catastrophic 71.6 percentage points below the UK average of 80%. The dangerous defect rate of 1.2% is mercifully low, but the near-universal failure on first test suggests these bikes arrive at MOT in genuinely poor condition.

The median mileage of 9,143 miles for a 23-year-old motorcycle is suspiciously low, indicating these are largely neglected or stored machines rather than regularly ridden vehicles. With an average of 0.2 failures and 0.3 advisories per bike, the pattern points to systematic decay from sitting idle—corrosion, fuel system gumming, and seized components—rather than wear from use. If you're considering one, budget for a full recommissioning by a specialist before riding it, because the odds of passing MOT without substantial work are essentially zero.

What to check before buying a 2001 Kawasaki Kmx125 B11

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.
