Should I check the MOT history before buying a 2018 KTM 790 Duke 18?

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 790 Duke 18?

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 790 Duke 18?

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.

Based on MOT data from 573 vehicles, the 2018 KTM 790 Duke 18 has a first-time MOT pass rate of 90.8%, 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 790 Duke 18?

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 790 DUKE is a solid performer in the MOT, passing first time at 85.0%, which is a clear 5 percentage point advantage over the UK average of 80.0%. The dangerous defect rate of 8.0% is reassuringly low, suggesting structural and safety issues are uncommon in this cohort.

These bikes are running relatively light at a median of 7,463 miles, which is modest for a six-year-old machine and suggests many are weekend warriors rather than commuters. With an average of just 0.47 failures per vehicle and 1.8 advisories, the 790 DUKE proves mechanically straightforward—when you're shopping for one, a full service history and a check on brake wear (a common advisory on sports bikes) should be your main focus.

The 2018 KTM 790 Duke 18 passes its MOT first time more often than most UK vehicles (90.8% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 90.8% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 1.8 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 573 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
