Motorex Racing Fork OilRACING FORK OIL with the new "3D RESPONSE TECHNOLOGY" which boasts a special molecular structure that facilitates innovative damping behaviour. This means that tractive and impact forces are no longer diverted along a zig zag path like an accordion, but are instead directed through a multi level grid structure. The three dimensional structure of the new molecular composition forms the basis of the 3D RESPONSE TECHNOLOGY Available Viscosity : 5W, 7.
