01What is motorcycle suspension sag?

  • Motorcycle suspension sag is the amount by which the suspension compresses when the weight of the rider and bike are applied to it.
  • There are two types of sag: static sag and rider sag. Static sag is the compression of the suspension when no weight is applied to it, while rider sag is the additional compression when the rider is on the bike.
  • Static sag helps determine the initial setup of the suspension, while rider sag is more specific to the rider's weight and riding style.
  • Having the correct sag settings can improve the bike's handling, stability, and overall comfort.

02Why is adjusting suspension sag important?

  • Adjusting suspension sag is important because it allows the rider to optimize the bike's performance and comfort.
  • If the sag is not properly set, the suspension may be too soft or too stiff, which can negatively affect the bike's handling and stability.
  • When the sag is set correctly, the suspension is in the optimal range for absorbing bumps and maintaining control.
  • Furthermore, adjusting sag can redistribute the weight between the front and rear suspension, ensuring a balanced ride and preventing excessive weight transfer during acceleration, braking, and cornering.

03How to adjust motorcycle suspension sag

  • To adjust the motorcycle suspension sag, follow these steps:
  • Step 1: Measure the static sag - Start by measuring the suspension's static sag, which is the compression when no weight is applied. This can be done by having someone hold the bike upright while you measure the distance between specific points on the motorcycle.
  • Step 2: Measure the rider sag - With the rider on the bike in their normal riding position, measure the compression of the suspension.
  • Step 3: Determine the required adjustments - Compare the measured sag values to the recommended sag settings for your motorcycle. This information can usually be found in the owner's manual or obtained from the manufacturer.
  • Step 4: Adjust the preload - Most motorcycles have preload adjusters, which allow you to increase or decrease the suspension's preload. Adjusting the preload will change the sag measurements.
  • Step 5: Repeat the measurements and adjustments - After making initial adjustments, remeasure the sag to ensure it is within the recommended range. If necessary, repeat the adjustments until the desired sag settings are achieved.
  • Step 6: Test and fine-tune - Take the motorcycle for a test ride to evaluate the handling and comfort. If further adjustments are needed, make small changes and test again.
  • Note: It is recommended to consult the motorcycle's owner's manual or a professional mechanic for specific instructions and recommended sag settings for your bike.

Conclusion

Adjusting the motorcycle suspension sag is a crucial step in optimizing performance, handling, and comfort. By following the proper adjustment procedures and determining the recommended sag settings, riders can ensure their bike performs optimally for their weight and riding style. Remember to take the time to measure, adjust, and test the sag to achieve the desired results. It may require some trial and error, but the benefits of a well-adjusted suspension sag are well worth the effort.
