External reservoir with hose connection Tuning the suspension Motorcycle road holding qualities All motorcycles are designed with a suspension geometry that includes height and fork angle. The changing of components can affect this and it is therefore essential that both the rear and the front ends match each other. -
Page 4: Function
3. Flow through 4. Piston with apertures needle valve Function The function, in principle, is that fluid is forced through needle valves at a low rate of flow (Fig.3) and through a number of apertures in the piston (Fig.4) at a high rate of flow. The flow through these apertures is regulated by shims (thin steel wash- ers, Fig.5) that at high pressure are deflected to open for the fluid. -

A-D. Bike on a stand. Settings Basic settings Always ensure that the basic setting made by Öhlins is correct. It is adapted to the make and model (in its original state) and for a rider of aver- age weight.

12. Rebound damping • Unstable • Hard • Loose • Bumpy • Bouncy Increase Setting your motorcycle NOTE! Always begin with the basic settings recom- mended by Öhlins. Always make notes, adjust in small steps and make only one adjustment at a time. -
Page 9: Adjusting The Shock Absorber Lenght
NOTE! Ensure that the springs are properly preloaded before attempting to make any adjustments. A simple rule is that increased preload of the spring should be followed by an increase of rebound damping by two steps. When you feel that you have achieved an im- provement, go back to where you started and check once more. -

17. Lift the bump rubber and clean the area below. Inspection and maintenance Clean the shock absorbers externally with a soft detergent. Use compressed air. Lift the bump rub- ber and clean the area below (Fig.17). Keep the shock absorbers clean and always spray them with oil (QS 14, WD40 or CRC 5-56 or simular). - Page 11 WARNING! Never alter the gas pressure. Special purpose charging equipment and access to nitrogen is required. The gas pressure should normally never be altered. WARNING! The shock absorber is provided with a separate type reservoir filled with high pressure nitrogen gas.
