2004 Yamaha Yn 50 Neo's
CarHunch analysed 144 real MOT records for the 2004 Yamaha Yn 50 Neo's. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2004 Yamaha YN 50 Neo's has a first-time MOT pass rate of just 23.8%, far below the UK average of 80%, making it a genuinely unreliable choice for a buyer seeking dependable transport. The dangerous defect rate of 3.5% is mercifully low, but the overall reliability picture is grim: you're looking at a scooter that fails its MOT roughly three times out of four on first attempt.
These machines average just 6,447 miles across their lifetime, so mileage isn't the culprit—this is about age and design. With 0.35 failures and 0.6 advisories per vehicle, the repeated problems tend to be minor niggles rather than catastrophic breakdowns, but that's cold comfort when you can't get through an MOT. If you're seriously considering one, budget for a pre-purchase inspection by a scooter specialist, not just a standard MOT check.
What to check before buying a 2004 Yamaha Yn 50 Neo's
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
