1972 Honda CB750K · Fork Tubes, Springs, Seals & Boots Buying guide

Build a fork order from the parts you inspect

The range includes internal service parts and external fork protection. Decide which components need replacement, then check tube application notes and package contents rather than ordering by model tag alone.

Parts to consider

Honda CB750 / CB650 / CB550 / CB500 Fork Seals Fork seal setListed seal dimensions are 35 × 48 × 10.5 / 11mm, with the 1972 CB750K included in fitment.View part Honda CB750 Progressive Type Front Fork Springs Progressive-type fork springsA set of two fork springs; the listing includes spacers and washers.

Read tube restrictions before choosing a length

The 585 mm tube set lists 1972 frames below 2093730. The 605 mm set lists frames above 2093730 and is expressly described as extended for that application. Neither description assigns exactly 2093730; confirm that boundary and the required length before ordering.

Count the separate fork-service pieces

The linked backup rings are supplied as a pair, reference 51452-319-010, and are described as sitting above the fork seals. The spring set includes its own spacers and washers. Keep these package contents separate when checking which service pieces are already covered by your order.

Common questions

Can I choose fork tubes from the model tag alone?

No. The tube descriptions contain restrictions that the broad category tag cannot express. Check the complete application notes and your installed forks. An unclear frame-number boundary should be confirmed before you select a tube set.

Do the progressive springs include spacers?

The featured spring listing describes a set of two springs with spacers and washers included. It does not list fork seals or gaiters as contents; those are separate products to consider according to the work needed.

Are all gaiters shown the same as the stock-type set?

No. The stock-type gaiter set and the shorter gaiter listing are described differently. Compare the product notes and the boots already fitted, including their attachment arrangement, before choosing the version for your motorcycle.
