The 2015 Yamaha YN passes its MOT slightly above the UK average at 83.3%, which is a solid result—but the 26.2% of vehicles that have recorded a dangerous defect is a red flag worth taking seriously, suggesting structural or safety issues have cropped up in roughly one in four examples. Petrol/diesel breakdown isn't relevant here since this is a motorcycle model.

These bikes are running at a median of just 5,680 miles, indicating most are relatively low-mileage examples, yet they're still averaging nearly one failure per vehicle and over three advisories—pointing to wear issues that aren't simply mileage-dependent. Before committing to purchase, have an independent inspection focus on the specific defects that triggered those dangerous flags, as they may indicate a systemic weakness rather than owner-neglect issues.

We have limited data for the 2015 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.
