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 SOFTAIL 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 SOFTAIL.

Pass rate by registration year

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 SOFTAIL FAQ

answers computed from the data above · terms in the glossary

Is the HARLEY-DAVIDSON SOFTAIL reliable?

The HARLEY-DAVIDSON SOFTAIL is about average for its class: 85.9% of its 1,609 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #2230 of 5426 models.

What does a SOFTAIL fail its MOT on most?

lighting and signalling — 29% of all defects recorded against failed SOFTAIL tests.

What is the best year of SOFTAIL to buy used?

By first-time pass rate, 2013-registered examples do best (94.8%) and 2006 worst (71.2%). Condition and history still trump the year.

How many miles will a SOFTAIL last?

The median SOFTAIL shows 15,489 miles at test, and examples around 50k miles still pass 79.1% of the time — mileage alone rarely kills one.
