Moderate sample. 328 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2018 KTM 390 Duke falls slightly short of the UK average, with a first-time MOT pass rate of 76.5% compared to 80%—suggesting you should budget for minor rectification work before testing. The good news is that dangerous defects are rare at 6.1%, so serious safety issues aren't a widespread concern with this model.

These bikes are running low mileage for their age at a median of 4,621 miles, which typically points to well-maintained leisure machines rather than hard-worked commuters. The average vehicle racks up just 0.3 failures and 1.1 advisories per test, indicating that when problems do emerge, they tend to be minor—so before buying, have any prospective Duke inspected by a motorcycle specialist to catch small issues before MOT day.

The 2018 KTM 390 Duke 18 passes its MOT first time more often than most UK vehicles (92.2% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 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 92.2% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔍 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 328 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.
