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 ZZR 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 ZZR.

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 ZZR FAQ

answers computed from the data above · terms in the glossary

Is the KAWASAKI ZZR reliable?

The KAWASAKI ZZR is less reliable than average for its class: 80.2% of its 5,103 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3531 of 5426 models.

What does a ZZR fail its MOT on most?

brakes — 34% of all defects recorded against failed ZZR tests.

What is the best year of ZZR to buy used?

By first-time pass rate, 2008-registered examples do best (94.1%) and 1991 worst (70.2%). Condition and history still trump the year.

How many miles will a ZZR last?

The median ZZR shows 28,782 miles at test, and examples around 50k miles still pass 74.0% of the time — mileage alone rarely kills one.
