How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the ZX 1000 GBF beats 3 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 ZX 1000 GBF.

Pass rate by registration year

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

Best year to buy used: 2011 (91.0% pass). Weakest: 2012 (89.3%).
