Please note: This bike is being re-listed due to a non paying bidder. Iconic takes this very seriously and the bidder has been banned from any further auctions with Iconic.
Introduced in the mid 1970s, the Honda CB400F was a thoughtful and sophisticated take on the small displacement sport motorcycle. Rather than chasing outright performance, Honda focused on refinement, balance, and everyday usability; qualities that set the CB400F apart from many of its contemporaries. With its compact proportions, light weight, and smooth power delivery, the model quickly earned a reputation as a rider’s bike rather than a spec sheet warrior.
Power came from a 408cc air cooled inline four paired with a relatively rare six speed transmission, helping the CB400F make the most of its modest output. Weighing just over 400 pounds, the bike offered nimble handling and predictable manners that made it equally at home commuting or carving through back roads. Period testers praised its smoothness and composure, noting that it felt more polished and cohesive than many larger, more powerful machines of the era. For more information, check out this story on Motorcyclist where they call it “the first real sportbike“.
Manufactured in March 1975, this example is VIN: CB400F1028896.
The odometer shows 10,738 miles.
The seller inherited this bike from his father, who had it for roughly a decade. He is selling off his father’s collection, which included a 1964 Rickman Metisse MkIII that he recently sold here on Iconic. “This bike belonged to my dad, Roger Riddell. It was a project bike and built to be a fun run around town bike.”
Maintenance:
In 2024, the seller had DK Motorcycle Center in Bountiful, Utah coat the fuel tank, rebuild the carbs, lube cables, replace the spark plugs, and perform a safety inspection.
In preparation for the listing, the seller had us perform a safety inspection, change the engine oil/filter, flush the hydraulic fluid, install a new front brake switch, clean/adjust/lube the chain, install new mirrors, and install a new left hand switch.
