KTM 390 Adventure 20 (2020)
2020 KTM 390 Adventure 20
CarHunch analysed 235 real MOT records for the 2020 KTM 390 Adventure 20. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 KTM 390 Adventure has a genuinely strong first-time MOT pass rate of 87.9%, nearly 8 percentage points above the UK average, and dangerous defects are rare at just 3.4% of the cohort. This is a reliable bike that consistently gets through its tests without major issues.
These machines are running modest mileage for their age—a median of 5,632 miles—which partly explains the clean sheet, but the real story is in the failure data: only 0.19 failures per vehicle and 0.6 advisories per vehicle tell you these bikes are mechanically sound out of the box. If you're considering one, check its service history and riding use; these bikes hold up well, but with this mileage profile you're as likely buying a lightly-used tourer as a well-thrashed one.
What to check before buying a 2020 KTM 390 Adventure 20
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.
