Should I check the MOT history before buying a 2014 Yamaha Yn?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

The 2014 Yamaha YN has a first-time pass rate of 78.1%, slightly below the UK average of 80%, which suggests middling reliability overall. More concerning is that 40.6% of these bikes have recorded a dangerous defect at some point—well above what you'd want to see—making pre-purchase inspection and maintenance history critical.

With a median mileage of just 6,929 miles, these machines are lightly used for their age, yet they're still averaging 1.34 failures per vehicle, which indicates underlying wear or design issues rather than just high-mileage wear-and-tear. The 3.9 advisories per bike (things like brake wear and light issues) are moderate, but given the low miles, budget for regular servicing and have any prospective purchase thoroughly checked by a qualified mechanic before committing.

We have limited data for the 2014 Yamaha Yn — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 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.
