Should I check the MOT history before buying a 2003 Yamaha Yq100?

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 Yq100?

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 2003 Yamaha Yq100?

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.

The 2003 Yamaha YQ100 has a 76.2% first-time pass rate, slightly below the UK average of 80%, which suggests moderate reliability concerns for a scooter of this age. Dangerous defects have been recorded in 15.5% of tested vehicles—not alarmingly high, but worth factoring into your inspection checklist before purchase.

These scooters show relatively low mileage at 10,995 miles median, which is healthy for their age and suggests many were either lightly used or well-maintained by previous owners. Expect around 1.6 failures and 3.3 advisories per test cycle, meaning routine maintenance and worn consumables are the norm—have a pre-purchase inspection focus on brakes, cables, and corrosion before committing.

We have limited data for the 2003 Yamaha Yq100 — treat the figures below as indicative rather than definitive.

⚠️ 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.
