Motorex Racing Fork Oil (SAE 7.5wt) 1 Litre RACING 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 in 2.5W / 4W / 5W / 7.5W / 10W / 15W
