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 ZZR600 beats 2 of its 4 closest rivals (KAWASAKI ZX-6R, SUZUKI GSF600, YAMAHA FZS600).

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 ZZR600.

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.

KAWASAKI ZZR600 FAQ

answers computed from the data above · terms in the glossary

Is the KAWASAKI ZZR600 reliable?

The KAWASAKI ZZR600 is less reliable than average for its class: 79.0% of its 53,666 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3770 of 5426 models.

What does a ZZR600 fail its MOT on most?

brakes — 38% of all defects recorded against failed ZZR600 tests.

What is the best year of ZZR600 to buy used?

By first-time pass rate, 2008-registered examples do best (91.2%) and 1990 worst (71.5%). Condition and history still trump the year.

How many miles will a ZZR600 last?

The median ZZR600 shows 25,618 miles at test, and examples around 50k miles still pass 71.4% of the time — mileage alone rarely kills one.
