Honda CB400 Four (1975 to 2027)

The Four models represent the variants of the CB400 family equipped with inline four engines, developed by Honda as mid displacement sport motorcycles with a focus on smoothness, high revs and mechanical refinement. The most representative model of this configuration was the Honda CB400F, produced between 1975 and 1977, which featured a 408cc inline four engine with SOHC valve train and air cooling, paired to a six speed manual transmission and chain final drive. This motorcycle was distinguished by its compact design, its characteristic 4 into 1 exhaust, and its ability to reach high revs, making it one of the most advanced sport bikes in its segment in the 1970s. Over time, the concept evolved in later models such as the Honda CB400 Super Four, which introduced liquid cooled DOHC engines and established itself as one of the standards for mid displacement naked motorcycles in the Japanese market.
