KTM 400 Exc (2005)
2005 KTM 400 Exc
CarHunch analysed 145 real MOT records for the 2005 KTM 400 Exc. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2005 KTM 400 EXC has a first-time pass rate of 73.5%, which trails the UK average of 80% by a meaningful margin, suggesting these bikes need more work to stay road-legal. The good news is that dangerous defects are relatively rare at 9%, so while reliability is below average, serious safety issues aren't a major concern for buyers.
These machines are typically ridden hard—the median mileage of 3,662 is relatively low for a 19-year-old vehicle, implying many examples have been stored or used intermittently rather than as daily transport. Each bike that fails MOT averages 1.54 failures and 4.4 advisories, pointing to wear across multiple systems rather than one glaring weakness, so budget for incremental repairs rather than expecting a single fix to solve MOT problems.
What to check before buying a 2005 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.
