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 RD500 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 RD500.

Pass rate by registration year

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

Best year to buy used: 1984 (91.4% pass). Weakest: 1986 (85.3%).

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.

YAMAHA RD500 FAQ

answers computed from the data above · terms in the glossary

Is the YAMAHA RD500 reliable?

The YAMAHA RD500 is more reliable than average for its class: 89.0% of its 1,955 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #1269 of 5426 models.

What does a RD500 fail its MOT on most?

lighting and signalling — 26% of all defects recorded against failed RD500 tests.

What is the best year of RD500 to buy used?

By first-time pass rate, 1984-registered examples do best (91.4%) and 1986 worst (85.3%). Condition and history still trump the year.

How many miles will a RD500 last?

The median RD500 shows 20,156 miles at test, and examples around 50k miles still pass 93.8% of the time — mileage alone rarely kills one.
