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.

The 2017 KTM 390 Duke 17 passes its MOT first time more often than most UK vehicles (90.5% 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 90.5% 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 726 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.
