Pass rate by mileage

how the FXDSE's first-time pass rate falls with the odometer · class average 84.9%

A low-mileage FXDSE passes first time 92.0% of the time; by 20k that's 88.2%.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the FXDSE beats 4 of its 4 closest rivals (HARLEY-DAVIDSON FLSTF, HARLEY-DAVIDSON FLSTC, TRIUMPH ROCKET III).

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 FXDSE.

Pass rate by registration year

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

Best year to buy used: 2007 (93.6% pass). Weakest: 2008 (92.2%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.
