Should I check the MOT history before buying a 2018 KTM 390 Duke 17?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2018 KTM 390 Duke 17?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2018 KTM 390 Duke 17?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2018 KTM 390 Duke 17 reliable?

Based on MOT data from 183 vehicles, the 2018 KTM 390 Duke 17 has a first-time MOT pass rate of 89.7%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2018 KTM 390 Duke 17?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2018 KTM 390 Duke falls short of the UK average, with a first-time pass rate of 74.0% compared to the national benchmark of 80%, suggesting slightly higher than typical fault rates for its age. Dangerous defects are present but not alarming, affecting 9.8% of the cohort—well below the worry threshold.

At nearly 6,500 miles on average, these bikes are running low mileage for a six-year-old machine, which typically indicates light use rather than mechanical stress. The 0.46 failures and 1.3 advisories per vehicle are modest figures, but the median Carhunch score of 50 reflects middling reliability; before buying, have a pre-purchase inspection focus on the specific failure patterns in the last two test cycles to catch emerging weak points early.
