Product Usage Instructions

Mounting Instructions

Put the motorcycle on a centre stand or work stand so that the rear wheel barely touches the ground. Ensure stability.
Remove the standard shock absorber by loosening the nut and washer from the lower mounting and screw and washer from the upper mounting. Repeat on the opposite side.
Reverse all procedures as necessary for mounting the new shock absorber.

Adjustments

Spring Preload Adjustments: Set the preload to 3 mm.
Compression Adjuster: Adjust to 20 clicks for optimal performance.
Rebound Adjuster: Adjust to 18 clicks for desired rebound settings.

Caution

Ensure all screws are tightened to the correct torque and that nothing restricts shock absorber movement when the suspension is fully compressed or extended.

FAQ

Q: What should I do if the shock absorber installation is too tight?
A: If the installation is too tight, use fine sandpaper to slightly reduce the diameter of the mounting studs for easier installation.
Q: Are the Compression and Rebound adjusters effective on the RH shock absorber?
A: No, due to low damping forces required for optimal road performance, the RH shock absorber has no damping function, making the adjusters ineffective when turned.

Note!
Before installing this product, check the contents of the kit. If anything is missing, please check an Öhlins dealer.

Please note that this image is a general representation of the product and may differ slightly from your product.
Note!
Please note that during storage and transportation, especially at high ambient temperatures, some of the oil and grease used for assembling may leak and stain the packaging. This is in no way detrimental to the product, wipe off the excessive oil/grease with a cloth.
Warning!
Before installing this product, read the Öhlins Owner’s Manual. The shock absorber is an important part of your vehicle and will affect its stability.

MOUNTING INSTRUCTIONS

Warning!
It is advisable to have an Öhlins dealer install the shock absorber.
Warning!
If working on a raised vehicle, ensure it is securely supported so that it will not tip over.
Note!
Before mounting this product clean the vehicle thoroughly.
Note!
When working on this product, always see the Vehicle Service Manual for vehicle-specific procedures and important data.

Put the motorcycle on the centre stand/work stand so that the rear wheel barely touches the ground. Make sure the motorcycle is in a stable position.
Remove the standard shock absorber by loosening the nut, washer ① from lower mounting and screw, washer ② from upper mounting.
Repeat the operation on the opposite side.
Install the Öhlins shock absorber by following the diagram as shown below (Diagram A).
Tighten the torque value as specified in the vehicle service manual.

Reverse all the procedures as necessary.

Note!
Due to manufacturing tolerances, it could occur that the Ohlins shock absorber installation may result in too tight at the upper and lower mounting studs.
(This situation is more likely to occur on vehicles with mounting studs of diameter greater than 11.992 mm) If you are experiencing such a situation, we recommend you utilize fine sandpaper to slightly reduce the studs’ diameter hence allowing the Ohlins shock absorber eyelets to slide thru the mounting studs more easily.

Note!
Lower the vehicle so that the suspension is slightly compressed before tightening the screws.
Caution!
Ensure that all screws are tightened to the correct torque and that nothing fouls or restricts the movement of the shock absorber when the suspension is fully compressed or extended.

ADJUSTMENTS

Warning!
Before riding, always make sure that the basic settings made by Öhlins are according to recommended Set-up Data. Read about adjustments and setting up in the Öhlins Owner’s Manual before you make any adjustments. Contact an Öhlins dealer if you have any questions about setting up.

Note!

Due to the low damping forces required for optimal road performance, the RH shock absorber has no damping function in it. Hence the Compression and Rebound adjusters will not be effective when turned.
For specialty use (Eg. Racing), reach out to an Öhlins service centre for restoring the full damping and adjustability function (not advisable for road use).
