1973 Honda CB450K · Rims, Spokes, Wheel Seals & Tire Valve Stems Buying guide

Compare the removed component and its exact wheel position

The front bearing states two used per wheel without clear pack quantity. Rear seal supply is one 34 × 55 × 9mm piece. Front retainer 44643-300-000 and rear retainer 41231-283-000 are separate products, with the rear identified for sprocket-side use.

Confirm the bearing contents before setting purchase quantity

The front bearing description states two used per wheel and asks buyers to order the number needed, without an unambiguous supplied-piece count. Inspect the service requirements and match 6302-2RS at the actual bearing. Confirm how many one purchase supplies before deciding the number of orders needed for both positions.

Check a changed hub from its own sealing requirements

The rear seal’s 34 × 55 × 9mm dimensions and one-piece supply identify this product. Compare the removed seal and fitted rear hub, particularly where the wheel was replaced. The original motorcycle application does not document every replacement hub or establish the front bearing and retainer requirements of that changed assembly.

CB450K buying questions

Does the front bearing’s two-used wording establish two bearings in one purchase?

It gives the required front-wheel count rather than clear supplied pack quantity. Confirm contents and inspect which positions need replacement, using the installed 6302-2RS marking as part of the comparison. Do not assume one purchase supplies both bearings or additional hub hardware.

What should I check before choosing a retainer for a substituted wheel?

Identify the actual hub and the retainer removed, then compare its front or sprocket-side rear position with 44643-300-000 or 41231-283-000 respectively. The two descriptions do not establish every replacement wheel’s fit or a bearing included with either retainer.

What size and quantity are stated for the rear wheel seal?

The rear wheel seal supplies one piece measuring 34 × 55 × 9mm, made in Japan by an OEM supplier. Compare the removed seal and its location in the fitted rear hub before ordering, especially where a replacement wheel is installed.
