The outer fork bushing (guide bushing) is fitted at the top of the fork leg, under the oil seal: together with the inner fork bushing (slide bushing), it guides the sliding of the fork. Its PTFE (Teflon) coating reduces friction; once worn, the bronze shows through, the fork binds and the oil seals wear out faster.

Specifications

• Brand: KYB
• Manufacturer part number: KYB-5104852
• Guide bushing fitted in the outer tube (PTFE-coated inside)

When to replace it?

• Grey coating worn through: the copper or bronze shows on the bushing.
• Play in the fork when you rock the bike back and forth with the front brake on.
• Fork that binds at the start of its stroke, oil seals that leak again and again.

Check the bushings every time you replace the oil seals or change the fork oil. Replace them as soon as the bronze shows over more than a quarter of their surface.

Fitting tips

1. Disassemble the fork leg following the manual and separate the outer tube from the inner tube.
2. Remove the old bushing without scratching its seat, and clean the seat.
3. Fit the new bushing with a suitable tool (or using the old bushing as a driver), then install new oil seals.
4. Reset the fork oil level as per the manual.

Why KYB?

Now one of the world's leading hydraulics specialists, with more than 15,000 employees, the brand describes its Gifu North plant, opened in 1968, as the largest shock absorber factory in the world.

Frequently asked questions

Do I have to change both bushings?
Check the outer and inner bushings on both legs: they wear together. Replace all those that show bronze.
