Should I check the MOT history before buying a 2003 Yamaha Tw125?

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 2003 Yamaha Tw125?

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

The 2003 Yamaha TW125 passes its MOT slightly above the UK average at 81.6%, which is a solid result for a 20-year-old bike. However, 16.4% of these machines have recorded a dangerous defect at some point, so mechanical inspection by a specialist before purchase is worthwhile.

These bikes typically show around 11,800 miles on the clock—reasonable for their age—but they average nearly two failures per test, suggesting wear components need regular attention. Check the service history carefully and budget for brake and suspension work, as the high advisory count of 6.9 per vehicle indicates these are systems that demand upkeep.

The 2003 Yamaha Tw125 passes its MOT first time at roughly the UK average rate (81.6%) — 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 6.9 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 318 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.
