Got a specific Yamaha Yq 50 Aerox you're checking out?
The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.
The 1999 Yamaha YQ 50 Aerox has a first-time MOT pass rate of just 7.6%, far below the UK average of 80%, which is a serious red flag for reliability. Dangerous defects are uncommon at 1.5%, but the overwhelming failure rate suggests these scooters are simply worn out or poorly maintained by this age.
At nearly 25 years old, the median mileage of 8,990 is actually quite low, meaning these machines have either been stored or used sparingly—yet still fail MOT at an alarming rate. The average vehicle racks up only 0.13 failures and 0.2 advisories per test, but because so few pass first time, you should expect to budget for multiple test attempts and repairs before getting one through; have a pre-purchase inspection done by a scooter specialist before committing.
We have 415 1999 Yamaha Yq 50 Aerox vehicles on record, but none have light-vehicle MOT history in our data source.
There are a few reasons this can happen:
- Heavy commercial vehicle — trucks, buses and coaches over 3.5 tonnes are tested under the DVSA annual HGV/PSV regime, which uses a separate database not included in our data source
- Imported vehicles — vehicles registered abroad and recently brought to the UK may have no UK MOT history yet
- MOT-exempt — vehicles manufactured before 1986 qualify under the 40-year rolling exemption; some specialist and agricultural vehicles are also exempt
- Never used on public roads — some vehicles are registered but kept off-road and have never required an MOT
