Should I check the MOT history before buying a 2012 KTM 125 Duke 12?

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 2012 KTM 125 Duke 12?

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 2012 KTM 125 Duke 12?

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 168 vehicles, the 2012 KTM 125 Duke 12 has a first-time MOT pass rate of 77.5%, 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 2012 KTM 125 Duke 12?

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.

This 2012 KTM 125 Duke has a first-time MOT pass rate of just 52.2%, significantly below the UK average of 80%, which is a serious warning sign for reliability. With 17.3% of these bikes having recorded dangerous defects at some point, you're looking at a model with genuine safety concerns that go beyond typical wear and tear.

At an average mileage of 11,731 miles, these bikes show relatively low usage, suggesting the poor pass rate isn't simply down to hard riding—something about the model itself is problematic. Owners face an average of 1.15 failures and 4 advisories per MOT, meaning even passing examples often need attention, so budget for regular maintenance and factor in potential repair costs before committing to buy.
