PROX Fork Bushing Kit for SUZUKI RM 125, RM 250 2000

The PROX 39.160040 fork bushing kit is designed for SUZUKI RM 125, RM 250 2000. This kit contains the fork's guide bushings: the outer bushing, at the top of the fork leg, and the inner bushing, at the bottom of the tube. Their PTFE (Teflon) coating reduces friction; once worn, the bronze shows through, the fork binds and the oil seals wear out faster.

Specifications

• Brand: PROX
• Manufacturer part number: 39.160040

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 bushings without scratching their seats, and clean them.
3. Fit the new bushings with a suitable tool, then install new oil seals.
4. Reset the fork oil level as per the manual.
