The 2006 Triumph Bonneville passes its MOT first time at 86.3%, which is a solid 6.3 points above the UK average of 80%, suggesting these bikes are generally well-maintained and reliable when they reach the test. With a dangerous defect rate of 13.9%, it's below the concern threshold and not a significant buyer worry.

The median mileage of just 8,559 miles indicates these are lightly used machines—typical of leisure bikes rather than commuters—which helps explain the strong pass rate. At 1.4 failures per vehicle and 4.1 advisories, the Bonnie tends to develop minor wear issues rather than structural problems, so budget for routine maintenance but expect no nasty surprises; check service history closely when buying, as these bikes reward regular care.

The 2006 Triumph Bonneville passes its MOT first time more often than most UK vehicles (89.2% 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 89.2% 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 4.1 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 935 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.
