The Honda CB400F Super Sport, introduced in 1975, was a significant step up from the CB350 it replaced. It featured a larger 408cc inline-4 engine and a distinctive 4-into-1 exhaust system that gave it a café racer look straight from the factory. The bike was praised for its smooth power delivery, light weight, and capable handling, making it an instant hit and a benchmark for middleweight motorcycles of its era. Later models from 1978 to 1981, like the CB400T Hawk twin and CB400A Hondamatic, are technically part of the family but are mechanically different and less sought-after by collectors.
Today, the CB400F is a cornerstone of vintage Japanese motorcycle collecting. Its appeal lies in its good looks, accessible performance, and the availability of parts for restoration. The market clearly favors the 1975-1977 Super Sport models, especially those with the original, undamaged exhaust system, which is incredibly difficult to find.
Market values for the CB400 series reflect this split. While project-quality Hawk twins can be found for as little as $1,000, perfectly restored CB400F examples command prices approaching $15,000. The average sale price sits around $6,600, indicating a healthy demand for good-quality, running bikes that either have their original components or are tastefully restored.
Buying Tips
- The original 4-into-1 exhaust on the CB400F is rare and expensive. Check if it's present and inspect it carefully for rust, dents, and repairs, as its condition heavily influences value.
- Listen for cam chain noise on startup, a common issue. Also, check for smoke from the exhaust, which can indicate worn piston rings or valve guide seals on these high-revving engines.
- Inspect the fuel tank for internal rust. These tanks are prone to corrosion if stored improperly, and finding a clean, original replacement is difficult.
- Verify the model. The 4-cylinder CB400F (1975-1977) is far more valuable than the 2-cylinder CB400T Hawk or the CB400A Hondamatic (1978-1981). Confirm the VIN and engine numbers.
Prices range from $1,000 for project bikes to $14,750 for pristine, restored examples.
