Pass rate by mileage

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

A low-mileage FLHTKSE passes first time 94.9% of the time; by 30k that's 89.1%.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the FLHTKSE 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 FLHTKSE.

Pass rate by registration year

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

Best year to buy used: 2015 (95.7% pass). Weakest: 2016 (89.9%).

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.
