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 CBR600 beats 2 of its 4 closest rivals (HONDA CBR600F, YAMAHA YZF-R6, SUZUKI GSXR600).

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 CBR600.

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.

HONDA CBR600 FAQ

answers computed from the data above · terms in the glossary

Is the HONDA CBR600 reliable?

The HONDA CBR600 is less reliable than average for its class: 79.4% of its 19,030 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3704 of 5426 models.

What does a CBR600 fail its MOT on most?

brakes — 25% of all defects recorded against failed CBR600 tests.

What is the best year of CBR600 to buy used?

By first-time pass rate, 2006-registered examples do best (90.3%) and 1987 worst (62.0%). Condition and history still trump the year.

How many miles will a CBR600 last?

The median CBR600 shows 25,845 miles at test, and examples around 50k miles still pass 74.2% of the time — mileage alone rarely kills one.
