Should I check the MOT history before buying a 1999 Honda Cg125?

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 1999 Honda Cg125?

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 1999 Honda Cg125?

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.

This 1999 Honda CG125 is a genuinely problematic buy—only 51.3% pass first time versus the UK average of 80%, meaning half of these bikes are limping into their MOT with defects that need fixing. The 10.8% dangerous defect rate is manageable, but the consistent failure pattern suggests these machines are either poorly maintained or wearing out badly.

At 17,375 miles median mileage, these bikes have racked up serious use for their age, and that burden shows in the average of 1.19 failures and 2.9 advisories per vehicle—typical wear items are clearly failing. If you're considering one, budget for immediate repairs and a full mechanical inspection before committing, because you're far more likely than not to inherit someone else's neglected maintenance backlog.

The 1999 Honda Cg125 passes its MOT first time at roughly the UK average rate (78.5%) — solid but worth checking this vehicle's history carefully.

⚠️ About 1 in 12 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 2.9 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 1,124 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.
