Should I check the MOT history before buying a 2011 KTM 125 Duke?

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 2011 KTM 125 Duke?

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 2011 KTM 125 Duke?

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 2011 KTM 125 Duke reliable?

Based on MOT data from 257 vehicles, the 2011 KTM 125 Duke has a first-time MOT pass rate of 78.2%, 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 2011 KTM 125 Duke?

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 2011 KTM 125 Duke has a first-time MOT pass rate of 60.2%, well below the UK average of 80%, which suggests these bikes accumulate genuine mechanical issues as they age. With nearly one in five having a dangerous defect on record (18.3%), potential buyers should factor in inspection costs and be prepared for remedial work before purchase.

At just over 11,000 miles on average, these machines are relatively lightly used for their age, yet they're still averaging 1.23 failures and 4.6 advisories per test—indicating wear rather than abuse-related problems. Before committing to one, have a pre-purchase inspection focus on the failures most common in this cohort, as the low pass rate suggests systemic weak points rather than one-off issues.

We have limited data for the 2011 KTM 125 Duke — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 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.
