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 XL1200S beats 0 of its 4 closest rivals (TRIUMPH BONNEVILLE, TRIUMPH THUNDERBIRD, HARLEY-DAVIDSON XLH 883).

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 XL1200S.

Pass rate by registration year

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

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 XL1200S FAQ

answers computed from the data above · terms in the glossary

Is the HARLEY-DAVIDSON XL1200S reliable?

The HARLEY-DAVIDSON XL1200S is more reliable than average for its class: 87.3% of its 4,163 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #1818 of 5426 models.

What does a XL1200S fail its MOT on most?

lighting and signalling — 26% of all defects recorded against failed XL1200S tests.

What is the best year of XL1200S to buy used?

By first-time pass rate, 2006-registered examples do best (92.0%) and 2004 worst (78.8%). Condition and history still trump the year.

How many miles will a XL1200S last?

The median XL1200S shows 11,102 miles at test, and examples around 40k miles still pass 81.5% of the time — mileage alone rarely kills one.
