1981 Honda CB400TB Suspension & Wheel Parts

The 1981 CB400TB uses air-assisted front forks, so fork caps, oil seals and dust boots deserve separate attention. This category also includes steering, swingarm and rear wheel service parts. Identify the assembly and original dimensions before choosing the parts for it.

1981 Honda CB400TB Hawk · Suspension & Wheel Buying guide

Match the service part to its assembly

A fork oil leak, steering bearing service and a rear wheel seal replacement require different parts. Start with the affected assembly and check whether the motorcycle still carries the original forks and wheels.

The air forks have several sealing points

The cap O-ring set supplies two replacements for 94608-50000. The oil seals sit lower in the fork and measure 33 × 46 × 11 mm; dust boots are another part again. Use Honda’s 1981 air-fork service instructions, including pressure-release precautions, before dismantling.

Inspect beyond the seal being replaced

The related steering conversion kit, swingarm dust caps and lower shock bushings address separate areas of the chassis. Identify play or wear before ordering; replacing a protective cap or dust seal does not renew the bearing or bushing that it covers.

Buying questions

Does the fork cap O-ring set also replace the air-hose seals?

No. It supplies the two cap O-rings referencing 94608-50000. The 1981 air-fork diagram identifies smaller O-rings for the air valve and hose connections separately, so inspect those locations when planning the work.

Is the rear wheel seal supplied as a pair?

The rear wheel seal is supplied as one piece, measuring 30 × 52 × 7 mm. Honda specifies one of this size in the original rear wheel assembly; compare the wheel if it has been replaced.

Are the 290 mm custom shocks a stock replacement choice?

The shortened custom shocks require their own mounting, travel, load and clearance assessment. A model filter alone does not establish those checks. Use a verified stock-length application or obtain a complete fit assessment before choosing a shortened setup.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
