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 CB600F beats 1 of its 4 closest rivals (HONDA CB500, TRIUMPH STREET TRIPLE, HONDA CB600 HORNET).

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 CB600F.

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 CB600F FAQ

answers computed from the data above · terms in the glossary

Is the HONDA CB600F reliable?

The HONDA CB600F is less reliable than average for its class: 81.9% of its 2,539 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3199 of 5426 models.

What does a CB600F fail its MOT on most?

lighting and signalling — 31% of all defects recorded against failed CB600F tests.

What is the best year of CB600F to buy used?

By first-time pass rate, 2007-registered examples do best (90.7%) and 1999 worst (73.6%). Condition and history still trump the year.

How many miles will a CB600F last?

The median CB600F shows 18,482 miles at test, and examples around 50k miles still pass 72.7% of the time — mileage alone rarely kills one.
