1973 Honda CB350F

Description

OFFERED WITHOUT RESERVE

The CB350F arrived in 1972 as Honda's answer to a simple question: what would a baby CB750 look like? The result was a genuinely clever piece of engineering — a 347cc inline-four crammed into a mid-size standard, complete with a four-into-four exhaust system that gave the bike a sound and presence well beyond its modest displacement. Production ran only through 1974, making the CB350F a relatively short-lived experiment in Honda's lineup, but one that has aged into a charming and mechanically interesting alternative to the more common twin-cylinder CB350.

The 347cc engine is fed by four 20mm Keihin carburetors and benefits from electric starting, a notable convenience at a time when many competing bikes still relied on a kick starter alone. Power is routed through a 5-speed manual transmission, with a single front disc brake and rear drum brake providing stopping power.

This 1973 CB350F is finished in Matador Red Flake and is presented in stock form. Acquired by the seller in 2025 following a multi-year hibernation, the bike has since received a round of mechanical attention, including servicing and polishing of the front forks, re-greasing the steering column bushings, and a rebuild of the carburetors, front brake caliper, and master cylinder, and more.

This 1973 Honda CB350F is offered at no reserve with an owner’s manual, the factory luggage rack, and Georgia registration in the seller’s name.

Ownership History

From the seller: "I purchased this CB350 Four from a gentleman here in Georgia, non-running after sitting for many years. He'd acquired it as part of a group of vintage Hondas and had confirmed it could run, but he wasn't quite up for the project of getting it road worthy. After a good bit of cleaning and servicing, and nearly 300 reliable miles to prove my work, it's time to send this CB350 Four on to its next owner."
