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
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
Best year to buy used: 1974 (91.0% pass). Weakest: 1971 (85.7%).
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 T500 FAQ
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.
