1974 Honda CB450K Rear Shock Set Comparison

Measure and identify the rear shock attachments on your 1974 CB450K before choosing a replacement set. The listed 321mm and 335mm options differ in length and stated contents. The shorter 290mm sets are custom applications, so their specific mounting form needs its own comparison.

1974 Honda CB450K · Shock Absorbers Buying guide

Match the mounting arrangement before choosing the shock finish

Chrome stock-design shocks measure 321mm centre-of-eye to clevis with five preload positions. The black 335mm eye-to-clevis set gives four and includes mounting pieces plus a wrench. Chrome 290mm shorty shocks are expressly custom eye-to-clevis applications.

Check the exact lower mount on every shorty choice

The selected chrome shorty uses an eye-to-clevis layout and gives a 12mm ID × 21mm upper bushing. The black eye-to-eye alternative instead gives 10mm ID × 21mm bushings at both ends. A shared 290mm length does not make these lower attachments interchangeable or establish stock replacement fit.

Build the hardware list from the chosen set’s contents

The 335mm descriptions include bushings, inserts, washers and a preload wrench. Those contents are not listed for every other family. Compare what the exact shock set supplies, then identify additional fasteners and rubber pieces needed; separate joint-rubber or nut listings do not establish a complete mounting kit.

CB450K buying questions

Which lower-mount measurements remain to check for the chrome eye-to-clevis shorty set?

The description gives the 12mm ID × 21mm upper bushing but not the lower clevis opening width or bolt diameter. Compare those lower attachment requirements on the motorcycle and confirm missing dimensions. Treat the 290mm set as a custom choice, not automatic replacement fit.

Can I assume the 321mm set supplies the same mounting pieces as the 335mm set?

The 335mm set explicitly lists bushings, inserts, washers and preload wrench, while the 321mm description does not give that contents list. Confirm the chosen purchase’s hardware and compare the mounts before deciding what to reuse or obtain separately.

Does the shock nut’s two-per-bike statement mean one purchase supplies both?

It states the quantity used, without explicitly defining a supplied pack count. Inspect which 90309-315-000 replacement nuts the repair needs and confirm purchase contents before setting the order quantity. The separate joint-rubber listing, by contrast, expressly supplies two rubbers.
