Service instructions for Ø50USD fork
GENERAL
The fork uses a multi-valve damping system with rebound and compres-
sion 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 damp-
ing.
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 pol-
ished inside.
SLIDING BUSHES: Teon
®
-coated, stiction-free.
SEALS: Computer-designed sealing rings ensure maximum
sealing on compression and minimal friction on re-
bound.
SPRINGS: Steel springs, different spring rates (K) available.
(See Table for more detailed information).
OIL: Special MARZOCCHI formulation prevents foam-
ing and retains same viscosity under any operating
conditions; stiction-free.
Use MARZOCCHI SAE 5 oil item no. 55 00 03 for
extremely cold weather.
SPRING TABLE
Fork static load is determined by the spring contained in each upper leg:
suspension response may be changed by changing the spring or the tube
spacer that determines its preload, with no need to alter fork settings.
“Spring+tube spacer” kits available as spare parts are listed below.
SPRING RATE K (N/mm) PART NO.
