KTM 390 Duke 17 (2017)
2017 KTM 390 Duke 17
CarHunch analysed 726 real MOT records for the 2017 KTM 390 Duke 17. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2017 KTM 390 Duke falls slightly below the UK average with a 77.1% first-time pass rate against 80%, suggesting marginally more reliability concerns than typical for its age. The good news is that dangerous defects are rare, affecting just 7% of vehicles tested, so safety-critical failures aren't a widespread problem with this model.
At just 4,569 miles median mileage, these bikes are relatively lightly used, which explains why the 0.44 average failures per vehicle is modest—though the 1.4 advisories per bike hint at minor wear items cropping up. If you're considering one, budget for routine maintenance to address those advisory items, and always request a pre-purchase inspection focusing on suspension and braking components, which typically account for the failures seen in this cohort.
What to check before buying a 2017 KTM 390 Duke 17
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.
