1976 Honda CB750F · Fork tubes, springs, seals & boots Buying guide

Choosing fork service parts and upgrades

Match seals, boots, springs and caps to the fork assembly fitted. Consider the separate damper-valve kit’s requirements before choosing it as an upgrade.

Service parts and supplied hardware

Spring set 27-1078 includes spacers and washers. Seal set 27-1007 is made in Japan and specified as 35 × 48 × 10.5 / 11 mm. Stopper rings replacing 51447-KL4-951 are a separate two-piece pack.

Fork cap reference and thread

Cap 29-6013 replaces Honda 90123-300-000, uses an M28 × 1.5 thread and is sold individually with an O-ring. Compare the fitted cap’s reference and thread when choosing a replacement.

Fork questions

What should I plan before choosing the damper valves?

The supplier requires damper-rod drilling and recommends installation by a mechanic. A 1-inch tube spacer may also be needed on some applications. Have the requirements for the fitted forks assessed before ordering.

Can I choose a cap wrench from the fork-tube diameter?

The 24 mm and 35 mm wrench listings both name the 1975–78 CB750F, while replacement cap 29-6013 links the 35 mm tool. The 35 mm wrench supplier asks buyers to measure the cap’s wrenching surface and confirm its shape, rather than choosing from fork-tube diameter alone. Match the tool to the exact cap fitted.
