How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the X DIAVEL beats 3 of its 4 closest rivals (TRIUMPH THUNDERBIRD, HARLEY-DAVIDSON FLSTF, HARLEY-DAVIDSON FLSTC).

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 X DIAVEL.

Pass rate by registration year

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

Best year to buy used: 2019 (90.8% pass). Weakest: 2017 (88.8%).
