About the Honda CB400

Find the right starting point for your Four, Hawk or Hondamatic repair.

Honda Motorcycle Logo

The Honda CB400 family brings together two very different engines. The original CB400 Four arrived in late 1974 with four cylinders, six speeds and a four-into-one exhaust. The CB400T followed as a separate twin-cylinder design. Identifying Four or twin is the first step toward choosing carburetor and engine parts.

Which Honda CB400 do you have?

For a Hawk, keep the complete T1 or T2 designation: the original Hawk I uses a front drum brake and the Hawk II a front disc. The CB400A Hondamatic is another distinct choice, with a torque converter and two-speed semi-automatic transmission. Use the model links below to reach the repair guide for your motorcycle.

Know your motorcycle before choosing partsHonda CB400 Four, Hawk and Hondamatic differences

Use the engine type and full model designation to choose the right collection.

Original Four · 1975–1977 parts

CB400F Four

Four cylinders distinguish the early Four from the Hawk twins. Its carburetor kits and overhaul gaskets have their own applications.

Parts checkpoint: Check the market and engine identity on an imported Four.

Honda CB400F Four parts

Twin-cylinder range

CB400T Hawk

CB400T carburetor kits divide into 1978–1979 and 1980–1981 applications. Select the year before comparing the kits.

Parts checkpoint: Keep a T1 or T2 suffix if it appears in your model identification.

Honda CB400T Hawk parts

Original front drum brake

CB400T1 Hawk I

The Hawk I uses a mechanical front drum brake. Fuel and clutch parts may have explicit coverage for both early Hawk variants.

Parts checkpoint: Choose brake parts for the assembly fitted to your T1.

Honda CB400T1 Hawk I parts

Original front disc brake

CB400T2 Hawk II

The Hawk II has a front disc brake. Its caliper, master cylinder and other hydraulic parts require a T2-specific check.

Parts checkpoint: A shared fuel tap does not establish brake interchangeability.

Honda CB400T2 Hawk II parts

1978 parts

CB400A Hondamatic

The Hondamatic combines a torque converter, two-speed semi-automatic transmission and parking-brake system.

Parts checkpoint: Use an explicit A application for transmission and control parts.

Frame, engine & fitted componentsHonda CB400 identification checklist

Use these details to match your motorcycle and any replacement assemblies before ordering.

  1. Record the complete frame/VIN and engine numbers, including their prefixes.
  2. Identify the original four-cylinder CB400F or a twin-cylinder T/A model.
  3. For a Hawk, confirm T1 or T2 and inspect the actual front brake; replacement forks or wheels can change the original setup.
  4. Copy the carburetor markings and note any engine, tank or front-end changes before choosing parts.
Need help identifying your CB400?

Contact PartsNMore with clear photos of the frame/VIN, engine number and the part’s markings, plus any known component changes.

Honda CB400 parts questions

Which Honda CB400 model should I select?
Select CB400F for the original Four, CB400T or the complete T1/T2 variant for a Hawk, and CB400A for the Hondamatic. Add the model year and compare the fitted engine and carburetor markings if components have been replaced.
Are CB400F and CB400T engine parts interchangeable?
The original CB400F is a four-cylinder motorcycle; the CB400T is a twin. Their carburetor and engine-gasket applications are different. Use the exact model and year shown on the part listing.
What is the difference between the CB400T1 Hawk I and CB400T2 Hawk II?
The original Hawk I has a front drum brake, while the Hawk II has a front disc. Some fuel and clutch parts list both variants, but brake, wheel and control parts still need the complete T1 or T2 application.
Can I use manual-Hawk clutch parts on a CB400A Hondamatic?
A conventional Hawk clutch listing is not enough. The CB400A uses a torque converter with a two-speed semi-automatic transmission. Transmission-related parts must explicitly cover the CB400A and its year.
