Moderate sample. 450 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2017 Triumph Thruxton is a genuinely reliable motorcycle, with a 93.7% first-time MOT pass rate that sits well above the UK average of 80%—and a dangerous defect rate of just 6.9% means buyers face minimal safety concerns. These bikes are rarely pushed hard: median mileage sits at only 4,830 miles for a seven-year-old machine, suggesting they're cherished rather than commuted on.

When failures do occur, they're typically minor (0.4 per vehicle on average), though the 1.8 advisories per bike hint at small wear items that need attention over time. If you're considering one, budget for routine maintenance on those advisory items, but rest assured the mechanical fundamentals hold up well—this is a solid buy for the retro-bike market.

The 2017 Triumph Thruxton passes its MOT first time more often than most UK vehicles (94.1% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 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 94.1% 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 1.8 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 450 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.
