The 2012 Triumph Thunderbird posts a 91% first-time pass rate—well above the UK average of 80%—which is genuinely reassuring, though the 21% dangerous defect rate does flag that one in five of these bikes will eventually develop a serious issue you can't ignore. This is a cruiser built for weekend riding, and the median mileage of just 9,865 miles confirms owners treat them as toys rather than commuters, which helps explain the strong MOT performance.

Failures average 0.91 per bike and advisories cluster around 4.1, suggesting when problems do emerge they're usually minor wear items rather than structural failures. If you're buying one, verify the service history carefully—these machines reward regular maintenance, and the low median mileage means you're likely to find examples with plenty of life left if the previous owner kept up with it.

We have limited data for the 2012 Triumph Thunderbird — 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.
