Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the FLHTK beats 4 of its 4 closest rivals (HARLEY-DAVIDSON FLSTF, HARLEY-DAVIDSON FLSTC, HARLEY-DAVIDSON XL1200C).

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 FLHTK.

Pass rate by registration year

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

Best year to buy used: 2014 (96.7% pass). Weakest: 2015 (94.0%).

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.

HARLEY-DAVIDSON FLHTK FAQ

answers computed from the data above · terms in the glossary

Is the HARLEY-DAVIDSON FLHTK reliable?

The HARLEY-DAVIDSON FLHTK is more reliable than average for its class: 93.5% of its 551 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #232 of 5426 models.

What does a FLHTK fail its MOT on most?

brakes — 22% of all defects recorded against failed FLHTK tests.

What is the best year of FLHTK to buy used?

By first-time pass rate, 2014-registered examples do best (96.7%) and 2015 worst (94.0%). Condition and history still trump the year.

How many miles will a FLHTK last?

The median FLHTK shows 14,752 miles at test, and examples around 30k miles still pass 93.3% of the time — mileage alone rarely kills one.
