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 DUKE beats 1 of its 4 closest rivals (HONDA CB500, TRIUMPH STREET TRIPLE, HONDA CB600 HORNET).

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 DUKE.

Pass rate by registration year

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

Best year to buy used: 2008 (93.8% pass). Weakest: 1998 (68.9%).

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.

KTM DUKE FAQ

answers computed from the data above · terms in the glossary

Is the KTM DUKE reliable?

The KTM DUKE is less reliable than average for its class: 79.7% of its 1,619 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3647 of 5426 models.

What does a DUKE fail its MOT on most?

lighting and signalling — 27% of all defects recorded against failed DUKE tests.

What is the best year of DUKE to buy used?

By first-time pass rate, 2008-registered examples do best (93.8%) and 1998 worst (68.9%). Condition and history still trump the year.

How many miles will a DUKE last?

The median DUKE shows 10,208 miles at test, and examples around 20k miles still pass 71.8% of the time — mileage alone rarely kills one.
