Should I check the MOT history before buying a 2005 Suzuki Gz125?

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.

The 2005 Suzuki GZ125 passes its MOT first time in just under 77% of cases, slightly below the UK average of 80%, and that's before considering the concerning fact that 30% of these bikes have recorded a dangerous defect at some point—a notably high proportion that should weigh heavily on any buyer's decision. This is a small commuter motorcycle, and the median mileage of under 10,000 miles suggests most examples have been used sparingly, yet they still average 2.56 failures per test, indicating age-related wear is catching up regardless of low use.

The high advisory rate of 7.7 per vehicle tells you these bikes accumulate minor niggles over time, even if they pass. Before committing to one, get a pre-purchase inspection that specifically checks the brake system, electrics, and fuel delivery—the usual trouble spots on 19-year-old commuters—and factor in the real likelihood you'll need work done within the first year of ownership.
