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 SPORTSTER beats 0 of its 4 closest rivals (TRIUMPH BONNEVILLE, TRIUMPH THUNDERBIRD, HARLEY-DAVIDSON XLH 883).

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 SPORTSTER.
