After introducing the four-cylinder string of lighter fours featuring [[engine]]s as small as 350 [[cubic centimetre|cc]] ([[Honda CB350F|CB350 Four]], [[Honda CB500|CB500 Four]]), and this 408 cc Four. | After introducing the four-cylinder string of lighter fours featuring [[engine]]s as small as 350 [[cubic centimetre|cc]] ([[Honda CB350F|CB350 Four]], [[Honda CB500|CB500 Four]]), and this 408 cc Four. | ||
For the most part, the CB400F was simply an upgraded version of the 350 model from the previous year. The most striking change was the swoopy four-into-one [[exhaust pipe|exhaust]] system that snaked around the frame, converging into a single [[muffler]] on the right side of the bike. Also noticeable were the angular fuel tank and flat cafe-style handlebars, all of which gave the bike a more racer-like look and feel than the rather pedestrian 350. | 4into1.jpg For the most part, the CB400F was simply an upgraded version of the 350 model from the previous year.

Although aimed at the sporting segment of the market, the CB400F came up a little short in the performance department compared to the competition, most notably the quick but noisy [[two-stroke]] triples from [[Kawasaki]]. But whatever the CB400F engine lacked in power it made up for in refinement, the small-displacement [[four-stroke]] being smooth and less audibly irritating than a two-stroke.

But whatever the CB400F engine lacked in power it made up for in refinement, the small-displacement [[four-stroke]] being smooth and less audibly irritating than a two-stroke. To help keep the engine in its power band, Honda employed a six-speed [[Transmission (mechanics)|transmission]]—something of a rarity at the time. | ||

Kaz Yoshima and other racers were able to take Honda's little 408cc engine up to 490cc and with the addition of other racer options, this small bore was considered a 'giant killer'. | ||
