How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the AN 400 X beats 3 of its 4 closest rivals (KAWASAKI ER5, SUZUKI GS500, SUZUKI AN400).

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 AN 400 X.

Pass rate by registration year

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

Best year to buy used: 1999 (86.3% pass). Weakest: 2000 (79.1%).
