KYB Complete Fork Free Piston for YAMAHA, HUSQVARNA, HONDA and KAWASAKI 2009-2026

The KYB KYB-3001005 complete fork free piston is designed for HUSQVARNA CR 125, TC 250, TC 449, TC 511, TE 250, TE 310, TE 449, TE 511, YAMAHA WRF 250, WRF 450, YZ 125, YZ 250, YZF 250, YZF 450, HONDA CRF 450 and KAWASAKI KXF 450 from 2009 to 2026. The free piston works with every movement of the fork. Once scored or tired, it lets oil past and the damping becomes inconsistent: a new complete piston puts the cartridge back in shape.

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.
