Service instructions for Ø48USD Kayaba fork - TC-TXC
GENERAL
The fork uses a multi-valve damping system with rebound and compression
adjustment and spring preload adjustment for static load.
Compression damping is controlled by a special valve located at the top of each
fork leg. Rebound damping is controlled by a sealed cartridge located inside
each inner tube.
Each fork leg has outer adjusters for compression and rebound damping.
Both fork legs have bleed valves to bleed air from the outer tube and drain
screws to drain cartridge oil.
INNER TUBES: Special high-strength steel, chrome-plated and TIN-coated.
OUTER TUBES: CNC-machined aluminium alloy, anodised and polished in-
side.
SLIDING BUSHES: Teflon
SEALS: Computer-designed sealing rings ensure maximum sealing
on compression and minimal friction on rebound.
SPRINGS: Steel springs, different spring rates (K) available. (See Table
for more detailed information).
OIL: Special KAYABA formulation prevents foaming and retains
same viscosity under any operating conditions; stiction-free.
Use SAE 5 oil for extremely cold weather.
SPRING TABLE
Fork static load is determined by the spring contained in each upper leg: suspen-
sion response may be changed by changing the spring or the tube spacer that
determines its preload, with no need to alter fork settings.
