2000 Yamaha Yq 50 Aerox

CarHunch analysed 639 real MOT records for the 2000 Yamaha Yq 50 Aerox. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2000 Yamaha YQ 50 Aerox is in serious trouble: only 12.6% pass their MOT first time, compared to the UK average of 80%, making it one of the least reliable vehicles in this age category. The dangerous defect rate of 2.7% is mercifully low, but the overall picture suggests these scooters are mechanically fragile or poorly maintained by their owners.

The median mileage of 10,421 miles is reasonable for a 24-year-old machine, yet vehicles are still averaging 0.2 failures and 0.4 advisories per test—indicating wear-related problems are widespread even at modest distances. If you're considering one, factor in regular maintenance costs and expect to spend time at a garage; this is genuinely a project bike, not a reliable runabout.

What to check before buying a 2000 Yamaha Yq 50 Aerox

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.
