How to Adjust Dirt Bike Suspension to Your Weight

One of the most important aspects of riding a dirt bike is having the suspension set up correctly for your weight. Proper suspension adjustment can greatly enhance your riding experience, providing better control, comfort, and overall performance. In this article, we will guide you through the process of adjusting your dirt bike suspension to your weight.

Step 1: Determine Your Sag

The first step in adjusting your suspension is to determine your sag. Sag refers to the amount the suspension compresses under the weight of the rider. To measure sag, you will need a friend to assist you.

1. Sit on your bike in your normal riding position, wearing your usual riding gear.
2. Have your friend measure the distance between the rear axle and a fixed point on the rear fender. This will be your starting point measurement.
3. Get off the bike and have your friend measure the distance again. This will be your new measurement with the bike unloaded.
4. The difference between the two measurements is your sag. Ideally, you should aim for a sag of around 25-30% of the total suspension travel.

Step 2: Adjusting Compression and Rebound Damping

Once you have determined your sag, you can adjust the compression and rebound damping to fine-tune your suspension.

1. Compression Damping: Compression damping controls how quickly the suspension compresses when hitting bumps or jumps. If you find the suspension is too stiff and not absorbing bumps well, you can reduce the compression damping. Conversely, if you are bottoming out easily, you can increase compression damping.
2. Rebound Damping: Rebound damping controls how quickly the suspension extends after being compressed. If you find the suspension is kicking back too quickly and causing the bike to bounce, you can increase rebound damping. If the suspension is extending too slowly, you can decrease rebound damping.

Step 3: Adjusting Spring Preload

Lastly, you can adjust the spring preload to further fine-tune your suspension. The spring preload affects how quickly the suspension reacts to weight transfer and how much sag is achieved.

1. If you find that you are not achieving the desired sag, you can increase the spring preload by turning the preload adjusters clockwise. This will increase the tension on the spring and decrease sag.
2. If you are achieving too much sag, you can decrease the spring preload by turning the adjusters counterclockwise.


Q: How often should I adjust my suspension?
A: Suspension settings can vary depending on the terrain, riding style, and your weight. It is recommended to make adjustments as needed, especially if you experience changes in your weight or riding conditions.

Q: Can I adjust my suspension myself?
A: Yes, you can adjust your suspension yourself with the proper tools and knowledge. However, if you are unsure or uncomfortable with making adjustments, it is best to consult a professional.

Q: What if I cannot achieve the desired sag?
A: If you are unable to achieve the desired sag range even with maximum spring preload adjustment, you may need to consider replacing the springs with ones that are better suited for your weight.

Q: Should I adjust the suspension differently for motocross and trail riding?
A: Yes, the suspension settings can vary for different types of riding. For motocross, you may want a stiffer setup for better handling and jumps. For trail riding, a softer setup can provide more comfort and traction.

In conclusion, adjusting your dirt bike suspension to your weight is crucial for optimal performance and comfort. By following the steps outlined in this article, you can achieve the desired sag and fine-tune your compression, rebound damping, and spring preload. Remember to make adjustments as needed and consult a professional if unsure. Happy riding!
