Should I check the MOT history before buying a 2003 Yamaha Yq 100?

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 Yq 100?

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 Yq 100?

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.

Is the 2003 Yamaha Yq 100 reliable?

Based on MOT data from 231 vehicles, the 2003 Yamaha Yq 100 has a first-time MOT pass rate of 80.7%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2003 Yamaha Yq 100?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2003 Yamaha YQ 100 is a genuinely poor performer on its first MOT attempt, with only 18.9% passing outright compared to the UK average of 80% — this is a scooter that will almost certainly need repairs before it clears the test. The dangerous defect rate is mercifully low at 0.9%, so safety isn't the primary concern; instead, expect widespread wear across brakes, lights, and emissions systems.

At 13,030 miles average, these machines have covered a reasonable distance for their age, yet they're still generating 0.18 failures and 0.2 advisories per vehicle on test. If you're considering one, factor in the cost of a full pre-purchase inspection and budget for at least one round of repairs before it will pass — buying one in MOT failure is the only sensible approach.
