The Triumph Bonneville Speedmaster has an overall MOT pass rate of 92.7% across 1,032 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
On the safety side, the most frequently flagged dangerous fault is brake pad(s) less than 1.0 mm thick. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Triumph Bonneville Speedmaster with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.
A typical Triumph Bonneville Speedmaster owner drives around 889 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
