Should I check the MOT history before buying a 1980 Yamaha Dt175?

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.

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.

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.

The 1980 Yamaha DT175 passes its MOT first time at 85.4%, which is a solid 5.4 percentage points above the UK average, suggesting these vintage bikes are generally well-maintained by their owners. Dangerous defects are rare at just 2.8%, so serious safety issues aren't a concern with this model.

These machines are running around 10,000–11,000 miles on the clock, which is reasonable for their age and suggests they're either cherished weekend rides or low-mileage survivors. With an average of 0.65 failures and 0.9 advisories per vehicle, expect minor wear items rather than structural problems—if you're considering one, get a pre-purchase inspection focused on fuel system condition and electrics, as those tend to be the weak spots on 40-year-old motorcycles.
