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
On first-time pass rate the K1100 beats 0 of its 4 closest rivals (BMW R1200, BMW R1150, TRIUMPH SPRINT).
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 K1100.
Pass rate by registration year
Best year to buy used: 1992 (84.6% pass). Weakest: 1998 (80.2%).
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.
BMW K1100 FAQ
Is the BMW K1100 reliable?

What does a K1100 fail its MOT on most?
brakes — 40% of all defects recorded against failed K1100 tests.
What is the best year of K1100 to buy used?
By first-time pass rate, 1992-registered examples do best (84.6%) and 1998 worst (80.2%). Condition and history still trump the year.
How many miles will a K1100 last?
The median K1100 shows 50,260 miles at test, and examples around 50k miles still pass 80.1% of the time — mileage alone rarely kills one.
