Should I check the MOT history before buying a 1998 Yamaha Sr125?

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.

Moderate sample. 374 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1998 Yamaha SR125 passes its MOT at 78.2%, just slightly below the UK average of 80%, putting it in unremarkable territory for reliability. Dangerous defects have occurred in 18.4% of examples, which is moderately concerning but not alarming—this suggests occasional serious issues rather than systemic problems.

These bikes average just over 19,000 miles, which is reasonable for their age and indicates they haven't been thrashed. The 1.98 average failures per test and 6.2 advisories signal that while problems do crop up, they're mostly minor wear items rather than catastrophic failures—if you buy one, budget for regular maintenance and budget for it.

The 1998 Yamaha Sr125 passes its MOT first time at roughly the UK average rate (78.2%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 6.2 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 374 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
