After Installing an Öhlins Shock Absorber/Front Fork

Note!
All motorcycles are designed with a suspension geometry that includes height and fork angle. Changing components (for example a shock absorber) can affect this and it is therefore essential that both the front and the rear ends match each other.  Changing to Öhlins suspension gives optimum performance only when both the front fork and the rear suspension interact properly. It is very important that the front and the rear loaded heights are within the specified values.

Note!
The springs in combination with the Öhlins shock absorbers contribute to superior stability and traction. See the Öhlins Recommendation List by contacting your nearest Öhlins dealer.

Warning!
If there are no matching springs for your motorcycle model, use the original springs, however, they must be in good condition and not fatigued.

FGK kits and Piston kits
Öhlins Racing also produces complete Racing Cartridge Systems, for front forks, as well as piston kits to upgrade your front fork to a higher performance level.

GO OUT FOR A TEST RIDE

Warning!
Before riding, always ensure that the basic settings made by Öhlins are intact. Take notes, adjust in small steps and make only one adjustment at a time.

General tips:
- Always begin your setting by taking a test ride with all adjustments at their recommended basic setting.
- Choose a short run of varying character, for example with long as well as sharp bends, hard as well as soft bumps.
- Adjust only one setting at a time. Go out for a new test ride.
- Take notes so that you can easily go back to an earlier setting if necessary.

Adjustments
Most Öhlins shock absorbers for motorcycle are equipped with spring preload, compression and rebound adjusters. The TTX44 also has a CSC adjuster. Due to limited space in some vehicles it is not possible to have all adjusters in certain models.
A deeper understanding for the different types of adjustments will give you a good knowledge of how you can get better performance from your Öhlins shock absorber.
When you adjust the spring preload, you move the spring seat. This will lower or raise the ride height.

Compression damping controls the energy absorption when the shock absorber is being compressed, thus controls how easy the shock absorber compresses when you hit a bump.

Rebound damping controls the energy absorption when the shock absorber is being extended and, thus controls how fast the shock absorber returns to its normal position after being compressed.

The Chassis Stability Control (CSC) adjuster (TTX44 models only) controls the average damping for both compression and rebound at slow movements. the adjuster is especially designed to control the chassis movements of the vehicle.

Warning!
Before riding, always ensure that the basic settings made by Öhlins are intact. Take notes, adjust in small steps and make only one adjustment at a time.

Warning!
Incorrect spring rate may result in a front geometry that is either too steep or too flat. This can result in a tendency of under or over steeing, that could seriously affect the handling characteristics of the motorcycle.

CSC, Rebound and Compression Damping
Start with the CSC adjuster Chassis Stability Control. This adjuster controls the average damping for both compression and rebound at slow movements. The adjuster is especially designed to control the chassis movements of the bike. If the bike feels loose and is transferring a lot of movement during acceleration and braking and/or if the bike feels nervous over bumpy sections close the CSC valve two [2] clicks. (If you are close to perfect setup click one click at the time. If the bike feels hard, harsh (no comfort) and is difficult to enter corners with or does not stay in line over bumpy sections, open the CSC valve two clicks. If you feel that there is not total damping enough at landings and when entering big bumps in high speed, close the CSC valve one [1] click at the time, be careful so that you do not loose the feel and stability of the bike.

Rebound damping
If you have got a good feeling for the bike with spring, preload and CSC valve and the ride height feels OK but the bike runs low and packs down under acceleration bumps, with lost line and/or lost comfort and traction, open the rebound adjuster two [2] clicks. If the bike is nervous and moving a lot or has a high feeling entering corners, even if the CSC valve has been adjusted, close the rebound adjuster two [2] clicks. Fine tune one [1] click at the time.

Test run and make the necessary adjustments. For original rebound setting see the Mounting Instructions for your shock absorber.

Compression damping
Do not change compression damping if you have not setup the CSC valve first. If the bike feels soft, is bottoming easy and you have the perfect spring for you, close the compression adjuster two [2] clicks. This will control the wheel during acceleration more, plus, it will help ride height and falling through the stroke at landings. If the bike feels high and is staying on top of small or medium bumps during acceleration open the compression adjuster two [2] clicks.

Test run and make necessary corrections. When you have sufficient feel of the motorcycle you can make further fine adjustments. It is feeling and experience that counts. When you feel that you have achieved an improvement, go back to where you started and check once more. Note other relevant factors such as tires, temperature etc. Test run to make sure whether further fine adjustments should be made.

Troubleshooting

Problem Try This
If the vehicle feels:
- Unstable Increase rebound damping
- Loose Increase rebound damping
- Bouncy Increase rebound damping
If the vehicle feels:
- Hard Decrease rebound damping
- Bumpy Decrease rebound damping
If the vehicle feels:
- Soft Increase compression damping
- Low Increase compression damping
- Bottoming Increase compression damping
If the vehicle feels:
- Harsh Decrease compression damping
- Hard Decrease compression damping
