Honda CB350 Four (1972 to 1975)

The CB350 Four was introduced in 1972 as the inline four engine variant of the Honda CB350. Notable for incorporating a mechanical architecture uncommon in its class at the time, the CB350F used a 347cc inline four engine with SOHC valve timing, air cooling, and four carburetors, allowing for exceptionally smooth operation and progressive power delivery. This engine was coupled to a five speed manual transmission with chain final drive and mounted in a lightweight, standard/sport style chassis characteristic of the CB family. Notably, the CB350F was one of the first small displacement motorcycles with an inline four engine, anticipating Honda's trend of offering multi cylinder configurations in increasingly accessible segments and solidifying the brand's technological reputation in the 1970s. The Honda CB350 F was produced until 1975.
