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 GPZ1000 beats 0 of its 4 closest rivals (TRIUMPH SPEED TRIPLE, APRILIA TUONO, HONDA CB1300).

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 GPZ1000.

Pass rate by registration year

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

Best year to buy used: 1988 (81.3% pass). Weakest: 1985 (71.2%).

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 GPZ1000 FAQ

answers computed from the data above · terms in the glossary

Is the KAWASAKI GPZ1000 reliable?

The KAWASAKI GPZ1000 is less reliable than average for its class: 76.7% of its 3,048 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #4095 of 5426 models.

What does a GPZ1000 fail its MOT on most?

brakes — 29% of all defects recorded against failed GPZ1000 tests.

What is the best year of GPZ1000 to buy used?

By first-time pass rate, 1988-registered examples do best (81.3%) and 1985 worst (71.2%). Condition and history still trump the year.

How many miles will a GPZ1000 last?

The median GPZ1000 shows 35,126 miles at test, and examples around 50k miles still pass 73.2% of the time — mileage alone rarely kills one.
