How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the ZEPHYR 1100 beats 1 of its 4 closest rivals (BMW R1200, BMW R1150, TRIUMPH SPRINT).

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 ZEPHYR 1100.

Pass rate by registration year
