How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the BLACK SHADOW beats 4 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 BLACK SHADOW.

Pass rate by registration year
