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 VZ800 beats 3 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 VZ800.

Pass rate by registration year

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

Best year to buy used: 2011 (92.7% pass). Weakest: 2002 (77.7%).

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.

SUZUKI VZ800 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI VZ800 reliable?

The SUZUKI VZ800 is about average for its class: 83.5% of its 11,772 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #2852 of 5426 models.

What does a VZ800 fail its MOT on most?

lighting and signalling — 27% of all defects recorded against failed VZ800 tests.

What is the best year of VZ800 to buy used?

By first-time pass rate, 2011-registered examples do best (92.7%) and 2002 worst (77.7%). Condition and history still trump the year.

How many miles will a VZ800 last?

The median VZ800 shows 13,866 miles at test, and examples around 50k miles still pass 66.2% of the time — mileage alone rarely kills one.
