Should I check the MOT history before buying a 1998 Yamaha Yq50?

The 1998 Yamaha YQ50 falls short of the UK MOT average, with a first-time pass rate of 73.6% against the typical 80%, suggesting these scooters are more prone to failures than the average vehicle. The 13.2% rate of dangerous defects is moderate but worth noting—just over one in eight of these machines have had a safety-critical issue.

At roughly 10,000 miles average, these scooters show relatively low mileage for their age, yet still rack up 1.25 failures and 2.7 advisories per test on average, indicating that wear and ageing matter more than miles for this model. If you're considering one, budget for brake and light work before purchase, and factor in regular servicing to keep it roadworthy—the median Carhunch score of 50 reflects a middling reliability picture.
