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 AN beats 4 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 AN.

Pass rate by registration year

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

Best year to buy used: 2017 (95.6% pass). Weakest: 2013 (87.1%).

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.

SUZUKI AN FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI AN reliable?

The SUZUKI AN is more reliable than average for its class: 90.7% of its 3,457 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #746 of 5426 models.

What does a AN fail its MOT on most?

brakes — 43% of all defects recorded against failed AN tests.

What is the best year of AN to buy used?

By first-time pass rate, 2017-registered examples do best (95.6%) and 2013 worst (87.1%). Condition and history still trump the year.

How many miles will a AN last?

The median AN shows 10,692 miles at test, and examples around 40k miles still pass 85.9% of the time — mileage alone rarely kills one.
