1974 Honda CB350F1 · Fork Tubes Buying guide

Measure the fitted tubes before ordering the pair

Fork tube replacement is more than a cosmetic chrome decision. Inspect the existing tubes and identify the remaining service parts for the actual fork assembly before placing the order.

Parts to consider

1972-74 Honda CB350 / CL350 Fork Tube Set ~ Replaces 51410-317-700 Fork tube pairTwo tubes, specified by the seller as 555 mm long and 33 mm outside diameter; reference 51410-317-700.View part

Use the reference and measurements together

Honda lists 51410-317-700 fork tubes for the F1, and the replacement pair carries that reference. The seller’s stated dimensions are 555 mm long and 33 mm outside diameter. Record the measurements of the fitted tubes rather than inferring length from model-year alone.

Plan the rest of the fork service

The purchase is a tube set of two, not an itemized complete fork rebuild package. Assess sealing surfaces and the remaining components during inspection. Match any seals to the original or modified fork’s specifications, with supplier confirmation when replacement dimensions differ.

Common buying questions

Are the fork tubes supplied as a pair?

Yes. The featured product is a set of two fork tubes. Its stated length is 555 mm with 33 mm outside diameter; compare those measurements with the installed front end before ordering.

Can I use the year alone to choose tube length?

No. A changed front end or previous modification can alter the required tube. The matching F1 reference is useful, but measure the actual assembly and confirm the intended replacement length.

Does the tube set include the fork seals?

It is described as two fork tubes, not a complete seal-and-hardware rebuild kit. Identify the required seals and other service parts separately for the fork assembly being repaired.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
