Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the THRUXTON beats 4 of its 4 closest rivals (TRIUMPH SPRINT, HONDA VFR800 FI, KAWASAKI ZX-9R).

Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the THRUXTON.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 2019 (93.7% pass). Weakest: 2006 (87.2%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.
