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 HERITAGE beats 0 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 HERITAGE.

Pass rate by registration year

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

Best year to buy used: 1994 (94.3% pass). Weakest: 1995 (90.0%).

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 HERITAGE FAQ

answers computed from the data above · terms in the glossary

Is the HARLEY-DAVIDSON HERITAGE reliable?

The HARLEY-DAVIDSON HERITAGE is more reliable than average for its class: 88.4% of its 773 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #1478 of 5426 models.

What does a HERITAGE fail its MOT on most?

lamps and reflectors — 21% of all defects recorded against failed HERITAGE tests.

How many miles will a HERITAGE last?

The median HERITAGE shows 13,702 miles at test, and examples around 50k miles still pass 91.3% of the time — mileage alone rarely kills one.
