Should I check the MOT history before buying a 2015 Yamaha Ns?

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.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2015 Yamaha NS passes its MOT first time at 80.5%, essentially matching the UK average of 80%, so reliability is broadly unremarkable—though the alarming 38.4% of these bikes have recorded a dangerous defect at some point, which should give prospective buyers serious pause about safety-critical components. With a median mileage of just 10,530 miles for a nine-year-old machine, these are lightly used examples, yet they're accumulating nearly four advisories per vehicle on average, suggesting age-related wear rather than neglect.

When you inspect one, budget for maintenance work: the average failure count of 1.2 means most will need at least minor rectification before MOT. Check the service history meticulously and have any bike independently assessed by a technician who can probe that dangerous-defect history—specifically brake, suspension, and lighting systems—before committing to purchase.

We have limited data for the 2015 Yamaha Ns — 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.
