The 2013 Triumph Bonneville is a genuinely reliable motorcycle, with a 91.7% first-time pass rate that sits well above the UK average of 80%—and the dangerous defect rate of 12.8% is reassuringly low. This is a bike that tends to stay roadworthy with proper care.

These machines are running low mileage for their age (median 6,599 miles), suggesting they're cherished rather than thrashed, and the average of just 0.77 failures per test confirms they're mechanically sound. If you're considering one, get a pre-purchase inspection focused on the electrics and exhaust system, since advisories average 2.4 per vehicle—common wear items on air-cooled classics.

The 2013 Triumph Bonneville passes its MOT first time more often than most UK vehicles (91.7% 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 91.7% 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 2.4 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 946 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.
