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 VZ 800 K5.

Pass rate by registration year

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

Best year to buy used: 2006 (89.0% pass). Weakest: 2007 (83.7%).
