The 1992 Honda CB400 passes its MOT at 80.5%, matching the UK average almost exactly, but nearly 23% of examples have recorded a dangerous defect at some point — a notably high rate that warrants careful inspection of any used bike you're considering. This suggests the model has inherent reliability issues rather than one-off problems, so structural or braking defects are a real buyer concern on these older machines.

With a median mileage of 34,723 miles for a 32-year-old bike, these CB400s have been ridden moderately and aren't typically run into the ground, yet they average nearly 2 failures and 6 advisories per test — indicating wear and age catch up with them regardless. Before purchase, get an independent pre-buy inspection focusing on the frame, brakes, and electrics, since the advisory rate suggests corrosion and component deterioration are commonplace.

We have limited data for the 1992 Honda Cb400 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
