1972 Honda CB450K · Shock Absorbers Buying guide

Compare the exact mounts before choosing a length or finish

The 335mm chrome set includes mounting accessories and a wrench, while the stock-design set states 321mm and five preload positions. The shorty family is custom. Separate OEM-type nuts and washers state two used per motorcycle without clear supplied pack counts.

Parts to consider

Related parts: OEM-type shock nut, reference 90309-315-000 · OEM-type shock washer, reference 90521-292-000 · Two joint rubbers, reference 52484-292-000

Use the mounting-parts references without assuming shared contents

The separate nut replaces 90309-315-000 and washer replaces 90521-292-000. Each describes two used per bike without clearly defining the supplied pack count. Compare the chosen shock set’s included accessories and the retained fastening arrangement before deciding which additional pieces and purchase quantities are needed.

Keep custom shorty mount forms distinct

Three shorty choices describe eye-to-clevis mounting with a 12mm ID × 21mm upper bushing. The black eye-to-eye version instead states 10mm ID × 21mm bushings at both ends. Identify the exact product and installed attachments; shared 290mm length does not make those mount forms interchangeable.

CB450K buying questions

Do two washers used per motorcycle arrive as a supplied two-piece pack?

The OEM-type washer description gives the motorcycle requirement, without a clear supplied pack count. Confirm purchase quantity for reference 90521-292-000 and compare the fastening pieces already included with your selected shocks before ordering separate washers for the repair.

Are the lower clevis dimensions stated for the chrome shorty set?

The listing gives a 12mm ID × 21mm upper bushing but not the lower clevis opening width or lower bolt diameter. Compare the actual lower attachment and confirm those dimensions before choosing the custom 290mm eye-to-clevis set.

Will selecting a product named stock length preserve the original ride height?

The available descriptions give different 321mm and 335mm measurements rather than one verified factory CB450K specification. Compare the intended setup, measurement method and mounts directly. The family name alone does not confirm the geometry or clearance of a changed installation.
