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 T500 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 T500.

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.

SUZUKI T500 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI T500 reliable?

The SUZUKI T500 is more reliable than average for its class: 87.9% of its 1,267 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #1639 of 5426 models.

What does a T500 fail its MOT on most?

steering and suspension — 29% of all defects recorded against failed T500 tests.

What is the best year of T500 to buy used?

By first-time pass rate, 1974-registered examples do best (91.0%) and 1971 worst (85.7%). Condition and history still trump the year.

How many miles will a T500 last?

The median T500 shows 19,025 miles at test, and examples around 50k miles still pass 87.5% of the time — mileage alone rarely kills one.
