Should I check the MOT history before buying a 2020 KTM 390 Duke 20?

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 2020 KTM 390 Duke 20?

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 2020 KTM 390 Duke 20?

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 2020 KTM 390 Duke 20 reliable?

Based on MOT data from 170 vehicles, the 2020 KTM 390 Duke 20 has a first-time MOT pass rate of 91%, 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 2020 KTM 390 Duke 20?

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 2020 KTM 390 Duke sits just below the UK average with a 78.6% first-time pass rate, so it's marginally less reliable than the typical car, though only 4.1% have ever suffered a dangerous defect—a reassuringly low figure. Petrol versions make up virtually all the sample and perform nearly identically at 78.7%, so fuel type isn't a reliability differentiator here.

With a median mileage of just 3,795 miles for a four-year-old bike, these Dukes are genuinely lightly used, suggesting they're being cherished rather than thrashed. The low failure count (0.28 per vehicle) and modest advisory rate (0.7) indicate that when these bikes do fail their MOT, it's usually minor—so budget for small fixes rather than major repairs.
