Honda CB400T Parts – Vintage Motorcycle Restoration & Custom Parts

Sort by

Looking for high‑quality Honda CB400T parts? Whether you ride a 1978, 1979, 1980 or 1981 CB400T, this collection includes everything you need to restore, maintain, or customize this standout twin from Honda’s late‑70s lineup.

The Honda CB400T was built around a 395cc air-cooled four-stroke parallel twin with a 360° crankshaft, 3-valve combustion chamber, dual balance shafts, and CDI ignition — all tuned for smooth torque delivery and strong midrange performance. Its distinctive over-square cylinder layout and balanced feel made it one of Honda’s most refined middleweights of the era.

Honda also introduced the innovative Com‑Star aluminum alloy wheels on the CB400T — tubeless-capable rims that were lightweight, rigid, and modern for their time. This model helped transition Honda from traditional spoked wheels into a new age of performance and durability, and it remains a unique blend of vintage character and advanced engineering.
