Should I check the MOT history before buying a 1998 Yamaha Sr 125?

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 1998 Yamaha Sr 125?

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 1998 Yamaha Sr 125?

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 253 vehicles, the 1998 Yamaha Sr 125 has a first-time MOT pass rate of 78.8%, 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 1998 Yamaha Sr 125?

The 1998 Yamaha SR 125 is a deeply unreliable motorcycle by modern standards, with just a 21.4% first-time MOT pass rate—less than a quarter of the UK average of 80%. Only 3.6% have ever suffered a dangerous defect, so catastrophic failures are rare, but the sheer frequency of issues makes this bike a genuine maintenance burden.

These machines have covered a modest 16,233 miles on average for their age, yet still accumulate 0.29 failures and 0.5 advisories per test, suggesting mechanical wear and neglect rather than hard use. If you're considering one, budget for regular repairs and expect to spend time in a workshop—this is a project bike, not a reliable commuter.
