1. What Is The Significance Of Sag Measurement In Suspension Tuning?
Sag measurement is crucial because it determines the initial position of your suspension, affecting how it responds to bumps and jumps. Correct sag ensures optimal suspension travel for both absorbing impacts and maintaining traction. Sag is the amount your suspension compresses under static (bike only) and dynamic (rider on bike) loads.
Understanding Sag Terms
- SAG: Originally stood for “Support And Gear,” now commonly refers to the amount of suspension compression.
- Extended SAG: Measurement of suspension at full extension (wheel off the ground).
- Static SAG: The amount the bike settles under its weight alone, without the rider. It is typically about 6-10% of total suspension travel.
- Race SAG: The amount the bike settles with the rider on board. Ideally, rear suspension SAG should be approximately 30-33%, and front SAG around 25-30% of the total suspension travel.
General Sag Percentage Guidelines:
- Front Suspension Static Sag: 14% of available travel (Travel in mm x 0.14 = Static Sag in mm)
- Front Suspension Rider Sag: 25% of available travel (Travel in mm x 0.25 = Rider Sag in mm)
- Rear Suspension Static Sag: 11% of available travel (Travel in mm x 0.11 = Static Sag in mm)
- Rear Suspension Rider Sag: 34% of available travel (Travel in mm x 0.34 = Rider Sag in mm)
Sag Measurement Tips
- Measure Accurately: Use a tape measure and have a friend help you. Measure from a fixed point on the frame to the axle.
- Consistent Technique: Ensure the bike is on level ground and the rider is in their normal riding position.
- Record Measurements: Keep a log of your measurements for future reference.
2. What Should I Check Before Adjusting Suspension Clickers?
Before tweaking your suspension clickers, verify baseline settings, tire pressure, spring rate, and proper installation to ensure you are making adjustments on a solid foundation. According to the Motorcycle Safety Foundation (MSF), in July 2025, verifying these settings provides a stable starting point for fine-tuning your suspension.
Pre-Adjustment Checklist:
- Record Current Settings: Note the current clicker positions in a notebook to track your adjustments.
- Tire Pressure: Adjust tire pressure based on the riding terrain, ensuring optimal grip and handling.
- Spring Rate: Confirm you have the correct spring rate for your weight and riding style.
- Sag Setting: Set the correct sag before making any clicker adjustments.
- Front Wheel Installation: Ensure the front wheel is installed correctly. Torque your triple clamps to the factory-suggested specification (typically 12Nm (106 inch/lb) for lower bolts and 17Nm (150 inch/lb) for the upper bolts). Over-tightening can bind the inner fork tubes.
- Air Bleed: Release air from the forks after each ride using the air bleed screw or aftermarket air release buttons, even on WP AER suspension forks. Check air spring pressure frequently.
- Maintenance: Regularly maintain your suspension by following the service intervals in your owner’s manual.

3. How Do I Adjust Suspension Clickers Properly?
To adjust suspension clickers properly, start with the factory settings, then adjust rebound and compression damping to suit your riding needs and terrain. Begin with compression damping, testing full firm and full soft to understand the adjustment range.
Step-by-Step Adjustment Guide:
- Consult Your Manual: Refer to your owner’s manual for suggested settings and specific instructions on adjusting rebound and compression for your fork and shock.
- Baseline Setting: Start with the clickers in the standard position recommended by the manufacturer.
- Compression Damping: Begin by adjusting the compression damping. Ride the bike with the compression adjuster set to full firm, then to full soft. This will give you a sense of the impact compression damping has on your ride.
- Rebound Damping: Repeat the same process with the rebound adjuster to understand its effects.
- Individual Adjustment: Adjust suspension damping for your weight, comfort, and the terrain.
- Track Your Changes: Keep a detailed notebook of all adjustments and their effects on handling.
Clicker Adjustment Tips:
- Small Increments: Make small adjustments (one or two clicks at a time) to avoid drastic changes.
- Test and Evaluate: After each adjustment, ride the bike to evaluate the changes.
- One Change at a Time: Adjust only one setting at a time to clearly understand its impact.
4. What Is The Role Of Rebound And Compression Damping In Suspension?
Rebound damping controls the speed at which the suspension returns after compression, while compression damping manages the resistance to compression. Balancing these adjustments is critical for optimal handling and comfort. Compression damping controls the force needed to compress the suspension, and rebound damping controls the rate at which the suspension returns to its original position after being compressed.
Detailed Explanation:
- Compression Damping: Manages the force required to compress the suspension, affecting how the bike handles bumps and landings.
- Rebound Damping: Controls the rate at which the suspension returns to its original position after compression, influencing traction and stability.
Low-Speed vs. High-Speed Compression Adjusters:
- Low-Speed Compression: Affects damping during slow shock velocities, such as rolling bumps and jump faces.
- High-Speed Compression: Controls damping during rapid shock movements, like square-edged bumps.
5. How Do I Adjust Suspension For Different Terrain Conditions?
Adjusting your suspension for different terrain conditions involves modifying compression and rebound damping to optimize traction and control. Soft terrain requires more compression damping, while hard-packed dirt benefits from softer settings.
Terrain-Specific Adjustments:
- Soft Terrain: Increase compression damping to handle larger, spaced-out bumps and increase rebound damping to minimize kick.
- Hard-Packed Dirt: Use softer settings for comfort and traction, as bumps are closer together and often have square edges.
- Muddy Conditions: Increase spring rates and compression damping to manage the extra weight.
Adjusting for Various Terrains
Terrain Type | Compression Damping | Rebound Damping |
---|---|---|
Soft/Loamy | Firmer | Firmer |
Hard Pack | Softer | Neutral |
Sandy | Firmer | Firmer |
Rocks/Roots | Softer | Faster |
Muddy | Firmer | Neutral |
Mixed Conditions | Blended Settings | Blended Settings |

- Solutions:
- Increase compression on the forks.
- Soften rebound on the forks to help them recover better.
- Adjust Shock Rebound:
- Be cautious, as too slow rebound can cause the shock to pack.
- Determine when the kick happens to better diagnose the issue.
- High-Speed Compression Damping:
- Soften high-speed compression to help the shock absorb bumps better.
- Try 1/8 to 1/4 turns at a time.
- Low-Speed Compression Damping:
- Soften low-speed compression to improve shock movement over rolling terrain.
- Adjust one or two clicks at a time.
- Rider Input:
- Ensure you are shifting your weight (butt) over the rear of the bike when braking.
8. What Are The Best Suspension Settings For Hard Pack And Square Edge Bumps?
For hard pack and square edge bumps, use the softest compression damping possible while maintaining control and preventing bottoming out.
Optimizing for Hard Pack:
- Softer Compression:
- Adjust compression damping to be as soft as possible to absorb square edges.
- Balance Control:
- Ensure you still have enough control to prevent bottoming out on jump faces and during G-outs.
9. How Does Fork Oil Height Affect Suspension Performance?
Adjusting fork oil height alters the air spring effect in your forks, making them more progressive and resistant to bottoming out.
Understanding Fork Oil Height Adjustments:
- Increasing Oil Height:
- Reduces the airspace in the fork’s spring chamber.
- Makes the forks feel more progressive and stiffer from mid-stroke onwards.
- Decreasing Oil Height:
- Increases the airspace, making the forks feel softer.
- Can be done by removing 10cc of oil at a time until bottoming out becomes an issue.
Benefits of Understanding Air Spring Function:
- Progressive Feel: Allows you to fine-tune the fork’s progression for better control.
