KTM 400 Exc (2006)
2006 KTM 400 Exc
CarHunch analysed 108 real MOT records for the 2006 KTM 400 Exc. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2006 KTM 400 EXC struggles at MOT time, with a first-time pass rate of just 64.3%—significantly below the UK average of 80%—suggesting these bikes need careful pre-test preparation and owners should budget for repairs. The 12% dangerous defect rate is manageable, but combined with an average of 1.37 failures per vehicle, these older machines demand attentive maintenance.
At just 3,524 miles median mileage, these bikes are lightly used for their age, yet they're still racking up 3.5 advisories on average, pointing to age-related wear rather than abuse. If you're considering one, factor in a full inspection by a specialist mechanic and expect to address minor issues before the next MOT—this is a bike that rewards preventive care.
What to check before buying a 2006 KTM 400 Exc
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.
