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 GPZ900R beats 0 of its 4 closest rivals (TRIUMPH SPEED TRIPLE, TRIUMPH STREET TRIPLE, APRILIA TUONO).

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 GPZ900R.

Pass rate by registration year

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

Best year to buy used: 1994 (91.6% pass). Weakest: 1995 (78.1%).

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 GPZ900R FAQ

answers computed from the data above · terms in the glossary

Is the KAWASAKI GPZ900R reliable?

The KAWASAKI GPZ900R is less reliable than average for its class: 81.4% of its 10,976 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3291 of 5426 models.

What does a GPZ900R fail its MOT on most?

brakes — 30% of all defects recorded against failed GPZ900R tests.

What is the best year of GPZ900R to buy used?

By first-time pass rate, 1994-registered examples do best (91.6%) and 1995 worst (78.1%). Condition and history still trump the year.

How many miles will a GPZ900R last?

The median GPZ900R shows 35,608 miles at test, and examples around 50k miles still pass 79.9% of the time — mileage alone rarely kills one.
