KYB Fork Cartridge Guide Bushing for free piston (bottom) for YAMAHA, HUSQVARNA, KAWASAKI and HONDA 2006-2026

The KYB KYB-3001103 fork cartridge guide bushing is designed for YAMAHA WRF 250, WRF 450, YZ 125, YZ 250, YZF 250, YZF 450, KAWASAKI KX 250, KXF 450, HUSQVARNA CR 125, TC 250 and HONDA CRF 450 from 2006 to 2026. In a fork cartridge, guide bushings keep the moving parts centred: the piston rod or the free piston, depending on the part number. Once worn, they allow play: the seals wear faster and the damping loses precision.

Specifications

• Brand: KYB
• Manufacturer part number: KYB-3001103
• Dimensions: 34.0 x 36.0 x 5.0 mm

When to replace it?

• Fork damping that changes during a ride.
• Oil getting where it shouldn't, cartridge oil level dropping.
• Seal hardened, marked or distorted when you remove it.

Replace this part at every full cartridge service, as set out in the fork manual. Check the diameter and dimensions listed: they must match your cartridge.

Fitting tips

1. Servicing a cartridge takes method and the right tools: follow the fork manual or leave it to a suspension specialist.
2. Strip the cartridge, clean all the parts and check the condition of the rod (scratches, pitting).
3. Fit the new part, oiled, without twisting it or damaging it on the threads.
4. Reassemble with fresh fork oil and carefully bleed the air out of the cartridge.
