The 2012 Triumph Bonneville is notably reliable, with a 92.7% first-time pass rate that sits well above the UK average of 80%, and only 13.2% of vehicles ever recorded a dangerous defect. This is a genuinely dependable bike if you find one that's been maintained.

The median mileage of just 6,402 miles suggests these are cherished machines, not daily commuters, which explains the low 0.73 average failures per vehicle. Before buying, check the service history carefully and budget for routine advisory items like fluid checks and wear parts—the 2.2 average advisories per test show that preventative maintenance keeps these machines running strong.

The 2012 Triumph Bonneville passes its MOT first time more often than most UK vehicles (92.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 8 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 92.7% 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 2.2 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 710 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.
