Should I check the MOT history before buying a 2004 Yamaha Dt 125 Re?

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 2004 Yamaha Dt 125 Re?

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 2004 Yamaha Dt 125 Re?

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 2004 Yamaha Dt 125 Re reliable?

Based on MOT data from 181 vehicles, the 2004 Yamaha Dt 125 Re has a first-time MOT pass rate of 82.1%, 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 2004 Yamaha Dt 125 Re?

The 2004 YAMAHA DT 125 RE is a reliability concern: just 18.3% pass first time against the UK average of 80%, meaning roughly four in five of these bikes show defects on their initial MOT. The dangerous defect rate sits at a low 1.7%, so while these machines are troublesome, they're not inherently unsafe.

At nearly 10,000 miles average, these bikes are ridden fairly hard for their age, yet they're still generating only 0.24 failures and 0.6 advisories per vehicle—suggesting the issues are frequent but minor. If you're considering one, factor in that it will almost certainly need work to pass MOT, and budget for repeated visits until any underlying wear is addressed.
