Should I check the MOT history before buying a 1999 Yamaha Yq50?

The 1999 Yamaha YQ50 falls short of the UK average, with a first-time pass rate of 71.3% compared to 80%—meaning you're more likely to face a failed MOT than with a typical vehicle. The dangerous defect rate of 17.1% is below the critical threshold, but it's still worth factoring into your decision.

These scooters are typically low-mileage machines at around 10,900 miles on average, yet they still accumulate nearly 1.4 failures and 2.9 advisories per test, suggesting age-related wear is catching up despite gentle use. Before buying, get a pre-purchase inspection focused on braking and suspension components—the most common failure categories on aging scooters—and budget for regular maintenance to keep it roadworthy.

We have limited data for the 1999 Yamaha Yq50 — 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.
