B233925 - 1 liter jug of MOTUL is our favorite brand of fork oil. This is a 100% synthetic ester based fluid reinforced with anti-friction additives, provides consistent suspension protection for safer and more precise handling. Its anti-foam, anti-corrosion and high viscosity index protects and preserves seals while guarding against wear and tear. This lt/med 7.5W oil is the PERFECT fluid for our 38mm Marzocchi and Ceriani forks, especially when using our Works Performance fork spring kit or our complete suspension package.
