The Triumph Bonneville Scrambler has an overall MOT pass rate of 86.7% across 2,260 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common problems on the Triumph Bonneville Scrambler are brake pad(s) less than 1.5 mm thick (10 recorded failures), tyre tread depth is below minimum requirements of 1.0mm (9), and exhaust markings indicating not for road use or similar wording (7). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
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 Scrambler 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 Scrambler owner drives around 505 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.
In terms of longevity, most Triumph Bonneville Scrambler models stay on UK roads for around 20 years — a strong showing that suggests solid build quality and readily available parts. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
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.
