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 ZX-6R beats 1 of its 4 closest rivals (SUZUKI GSF600, YAMAHA FZS600, SUZUKI SV650S).
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 ZX-6R.
Pass rate by registration year
Best year to buy used: 2012 (88.6% pass). Weakest: 1994 (68.3%).
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.
KAWASAKI ZX-6R FAQ
Is the KAWASAKI ZX-6R reliable?
The KAWASAKI ZX-6R is less reliable than average for its class: 78.1% of its 173,953 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3896 of 5426 models.
What does a ZX-6R fail its MOT on most?
lighting and signalling — 25% of all defects recorded against failed ZX-6R tests.
What is the best year of ZX-6R to buy used?
By first-time pass rate, 2012-registered examples do best (88.6%) and 1994 worst (68.3%). Condition and history still trump the year.
How many miles will a ZX-6R last?
The median ZX-6R shows 19,446 miles at test, and examples around 50k miles still pass 69.0% of the time — mileage alone rarely kills one.
