FDS – 250 Series
．Preload adjuster
　Please use a 12mm socket to adjust. One full turn equals 1mm, with a maximum range of 10 ± 0.5mm. The side of the adjustment rod has markings for convenient and quick setup.
．NTN needle bearing
　Built-in NTN needle bearing to reduce friction when adjusting the preload.
．Lightweight preload spacer
　Note: When installing, ensure the black plastic side faces the spring. After calculating the required stroke, use the lightweight spacer to replace excess spring length.
．Reinforced spring
　The spring is made of SAE9254 silicon steel, allowing for the production of lightweight springs with larger wire spacing.
．High-sensitivity valve piston ( W.R.V.P )
　Precisely calculated high-sensitivity valve shim settings, combined with a large piston featuring independent one-way damping for rebound and compression, provide the necessary damping force during low, medium, and high-speed operation. This eliminates excess simple harmonic motion (S.H.M) and provides the tire with maximum normal force and maximum static friction at all times.
．Compact size + lightweight piston rod
　The piston rod volume is reduced to increase the internal oil volume of the fork, stabilizing oil temperature and damping force. The piston rod is made of high-tensile aerospace-grade aluminum to achieve weight reduction.

※The vehicle model may have different specifications in different regions and may not be compatible for installation.
