Moderate sample. 404 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2014 Triumph Thunderbird is notably more reliable than average, with a first-time MOT pass rate of 91.2% against the UK average of 80%—a solid result for a decade-old motorcycle. However, nearly one in four owners (22.3%) have encountered a dangerous defect during their MOT history, which is worth taking seriously and suggests some specific wear items need close inspection on any example you're considering.

The median mileage of just under 10,000 miles is very low for a nine-year-old cruiser, indicating these are often weekend machines rather than daily commuters, which bodes well for longevity. Most vehicles average fewer than one failure and less than three advisories across their MOT lifetime, but the relatively modest Carhunch score of 50 suggests you should get a thorough pre-purchase inspection focusing on the fuel system, electrics, and exhaust components—the areas where this model has historically shown problems.

The 2014 Triumph Thunderbird passes its MOT first time at roughly the UK average rate (91.2%) — solid but worth checking this vehicle's history carefully.

⚠️ 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.

For context
Good baseline reliability. A 91.2% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 2.8 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 404 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
