1972 Honda CB450K · Suspension & Wheel Buying guide

Keep fork, shock and hub measurements with the correct component

The cap replaces 90123-323-010 and is sold each, without a stated thread dimension. The featured chrome shocks measure 335mm eye-to-clevis. The rear seal supplies one 34 × 55 × 9mm piece; steering and pivot hardware remain separate purchases.

Parts to consider

Compare listed shock families from their actual dimensions

The stock-design chrome set specifies 321mm center-of-eye to clevis, while the stock-length family specifies 335mm eye-to-clevis. Shorty sets are 290mm custom choices with different mount forms. Match the intended arrangement to the exact product rather than treating those family names as a factory CB450K length specification.

Prepare a separate contents check for each service area

The cap supplies its O-ring, and the rear seal states one piece. Front bearing wording instead gives two used per wheel without clear supplied quantity. Inspect the components needed for the work and confirm each package, avoiding assumptions that a selected cap, shock set or seal completes another assembly’s repair.

CB450K buying questions

Can a different fork cap’s thread measurement be used for this top bolt?

This 90123-323-010 replacement does not state a thread diameter or pitch. Compare the fitted fork and confirm those missing dimensions where needed. A thread specification attached to another cap reference does not verify the connection of this product.

Does the shock set’s included washer list identify the separate OEM-type washer?

The 335mm set names included washers without identifying them as reference 90521-292-000. Compare the required fastening pieces and exact contents. The separate OEM-type washer listing is not automatically proof that it duplicates a washer supplied with the shock set.

Does one front bearing purchase cover both positions in the wheel?

The listing states two 6302-2RS bearings used per front wheel without clearly defining supplied package quantity. Compare the installed bearing marking, identify the pieces needed for the repair and confirm purchase contents before assuming one order covers both positions.
