Öhlins Cake Kalk Suspension Manual, In this manual, mounting instructions and other technical documents, important information concerning safety is distinguished by the following symbol. 1Note!
Read and ensure you understand the information in this manual and other technical documents provided by the vehicle manufacturer before using the product.
When movement of the motorcycle causes compression of the front fork/shock absorber,the ﬂuid ﬂows through the needle valve (combined compression and rebound valve) in the piston rod. If the velocity of the compression movement is high, i.e., in the case of rapid compression, this will not be suﬃcient and consequently the shims underneath the piston will open to allow for a greater rate of ﬂow. The ﬂuid that is displaced by the volume of the piston rod is forced into the external reservoir via a separate compression valve. The separating piston is displaced, thus increasing the gas pressure.
When the spring forces the front fork/shock absorber to extend again, the ﬂuid ﬂows back through the needle valve. The ﬂuid ﬂowing into the chamber is forced by the pressure of thegas back into the front fork/shock absorber via a separate non-return valve. If the piston velocity is high, the shims on top of the piston will also open to allow the ﬂuid to ﬂow through.
Set rampup chamber air pressure(If existing on your fork)
Unscrew the cap on the bottom of the right front fork leg and connect the air pump tothe lower valve (ramp up chamber). Pump to recommended pressure. Disconnect the air pump and tighten the air cap.
Set main chamber air pressure
Unscrew top air cap on the right front forkleg and connect the air pump to the main chamber valve. Pump to recommended pressure. Compress and extend the fork 10 times to equalize the pressure in the fork leg.If the pressure has decreased, then pump to recommended pressure. Disconnect the air pump and tighten the air cap.The recommended pressures can be seen in chapter Setup Data.
Compression damping controls the energy absorptionwhen the front fork is being compressed, thus controls how easily the front fork compresses when you hit a bump. Rebound damping controls the energy absorptionwhen the front fork is being extended and controls howfast the front fork returns to its normal position after being compressed.
To set the adjusters
Turn the adjuster clockwise to fully closed position. Then, turn counter clockwise toopen, and count the clicks until you reachthe recommended number of clicks. The recommended number of clicks can be seen in chapter Setup Data.
Compression damping adjuster
- Adjust low speed: To adjust, turn the blue coloured adjuster on the top of the left front fork leg. Turn clockwise to increase damping, turn counter clockwise to decrease.
- Adjust high speed: To adjust, turn the black coloured adjuster on the top of the left front fork leg. Turn clockwise to increase damping, turn counter clockwise to decrease.
Maintenance and regular inspection reduces the risk of poor performance. If there is any need for additional service, contact an authorized service center.
Clean the front fork and the shock absorber externally with a mild detergent. Use compressed air. Make sure to remove all dirt after every ride. Lift the shock absorber´sbump rubber and clean the area below. Keepthe shock absorber clean and spray it with oil (WD40, CRC 5-56 or equivalent) after washing.
