Description
HONDA CB 400 FOUR competition bike for series-derived racing from the 1970s.
The enlarged 400 was preferred to the 500 because the 400 was far more modern than the Four 500,
it was lighter, and featured a 6-speed gearbox.
The one we're offering is PRESERVED, we've simply cleaned it up.
We don't know the name of the rider who used it, nor the tuner.
But whoever prepared this bike knew what they were doing and how to do it.
Enlarged engine, larger and further worked carburettors,
bike super lightened, square swingarm etc. etc.
