KYB Complete Fork Free Piston for SUZUKI RMZ 250 2019-2027

On SUZUKI RMZ 250 from 2019 to 2027, the KYB KYB-3001009 complete fork free piston fits in place of the original part. 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.
