vs expected · age & mileage

The pass rate is the MOT first-time pass: a roadworthiness check of the items an MOT covers (brakes, lights, tyres, steering, structure, emissions), not a full mechanical inspection of engine or gearbox internals. It is a reliability signal, not a complete measure of mechanical reliability. What this measures.

“vs expected” adjusts for age, mileage and test class, so a cherished classic and a hard-used commuter are compared fairly. How this works.

Pass rate by registration year

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

Best year to buy used: 1998 (78.9% pass). Weakest: 1993 (68.8%).

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 RF600 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI RF600 reliable?

The SUZUKI RF600 is less reliable than average for its class: 73.0% of its 6,870 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #4498 of 5428 models.

What does a RF600 fail its MOT on most?

brakes — 34% of all defects recorded against failed RF600 tests.

What is the best year of RF600 to buy used?

By first-time pass rate, 1998-registered examples do best (78.9%) and 1993 worst (68.8%). Condition and history still trump the year.

How many miles will a RF600 last?

The median RF600 shows 25,665 miles at test, and examples around 50k miles still pass 76.3% of the time — mileage alone rarely kills one.
