The CB350 Four was Honda's smallest four-cylinder road bike, a scaled-down CB500/750-style machine aimed at riders who wanted four-cylinder smoothness more than outright performance. It was quieter, heavier and less punchy than the CB350 twin, but had a front disc brake and four exhausts; the 1973 bike was unchanged from 1972.
