How to Adjust Dirt Bike Suspension to Your Weight

If you’re new to dirt biking, you may be wondering how to adjust your bike’s suspension to your weight. Sag, or “shock adsorption gauge,” is a common adjustment that allows you to adjust how far the bike drops when you’re riding. Setting your bike’s sag is simple, but requires two people to do it correctly. Read on to find out how to set your bike’s suspension to your weight.

Preload off the shock spring

You can adjust your dirt bike suspension to suit your weight by adjusting the preload of the spring. This spring adjustment varies the stiffness of the fork and shock. When the preload is high, the bike is raised, while when it’s low, it falls. Changing the preload can alter the handling and trail of your bike. Likewise, adjusting the spring’s length can affect the bike’s weight and stiffness.

To adjust the spring preload, you first need to measure sag, or the amount of travel the suspension takes in a single stroke. To get the percentage value, divide the sag measurement by the shock stroke. Next, adjust the spring stiffness. To do this, turn the collar of the spring and adjust its preload to match your weight. If you’re using an air shock, you can adjust the preload by adding more air.

Correct fork spring rate

Regardless of weight and riding style, there are many variables when setting up your dirt bike’s suspension. You may think your bike is set at just the right level, but this is not necessarily the case. The correct fork spring rate will help you adjust your dirt bike’s suspension to your weight, and there are some basic steps that you should follow to get the right balance. A good place to start is with the ride height. It’s important to remember that your bike’s ride height will determine how high you ride it.

To determine if your bike is adjusted to the correct weight, measure the height of the seat and then lean the bike up against something. If you don’t feel comfortable doing this alone, enlist a friend to help you. Push down on the seat to compress the shock and then let it rise naturally. Once you’ve measured the height of your bike, take a second measurement. Your second measurement should be 600mm and 30mm.

Correct shock spring rate

One of the most important parts of your dirt bike’s suspension is choosing the correct shock spring rate. This will allow you to achieve the appropriate sag rate, which is how much the shock or fork compresses during riding. This amount is typically measured in millimeters. A good rule of thumb is to have between 30 and 35 millimeters of sag in the front and rear.

You can also adjust the rebound damping to minimize the trampoline effect. To achieve this, you can dial in the rebound damping a few clicks and keep adding them until the suspension extends once. Make sure to adjust compression damping as well, as not all suspension components have this feature. If your bike bottoms a lot, you might need to adjust the spring rate further. Fortunately, some motorcycles have a bottoming out stopper on the side of the shock.

Correct damper rate

The correct damper rate to adjust dirt bike suspension to fit your weight depends on your riding style. For example, if you ride motocross, you want the suspension to be relatively balanced between the front and rear. You’ll want to be comfortable while riding, and the suspension to be firm but not bouncy. To set the correct damper rate, follow these simple steps. First, lift the rear end off the ground and check the sag. Ideally, the rear should be between 0 and fivemm.

Compression damping adjusts how much the suspension compresses when riding over bumps. Lower compression damping makes the suspension soft, while higher compression damping makes the rider feel sharp. The compression damping in a dirt bike suspension is regulated by a small screw on the rear shock body and on the fork cap. The screw is usually marked, and you can adjust the rate by rotating the screw counterclockwise.
