How To Adjust Dirt Bike Suspension To Your Weight

Dirt bike riding is an exhilarating experience. However, having a properly adjusted suspension system can make all the difference in your comfort and safety on the trails. When your dirt bike suspension is customized to your weight, it greatly improves your riding experience, allowing you to tackle various terrains with ease and confidence.

Getting your suspension dialed in can seem daunting, but with some essential steps and a bit of patience, you'll be ready to hit the trails in no time. The key to adjusting your dirt bike suspension lies in understanding the sag, which is the amount of suspension compression when you're seated on the bike.

A correctly set sag ensures that your bike is responsive to bumps and jumps, providing optimal traction and handling on different surfaces. As a rider, it is essential to know your weight, as this directly affects the sag and the overall dirt bike suspension setup.

Steps on How to Adjust Dirt Bike Suspension to Your Weight

In this section, we’ll discuss the steps to adjust your dirt bike suspension according to your weight. We will cover five main steps: measuring your weight, setting sag properly, adjusting compression and rebound damping, fine-tuning preload settings, and testing and iterating until you find the perfect balance.

Step 1: Measure Your Weight

Before making any adjustments, knowing your weight is essential, as it will serve as the reference point for other changes. Make sure to measure your weight while wearing all your riding gear, as this will more accurately represent the load the bike needs to support.

Step 2: Set Sag Properly

Setting your dirt bike sag properly is essential in adjusting the suspension to your weight. Sag refers to how much your bike "sags" under your weight when you sit on it.

To set sag correctly, follow these steps:

  1. Place your dirt bike on a stand with the rear wheel off the ground and fully extended.
  2. Measure a point on the swing arm up to the rear fender, noting the measurement as M1.
  3. Get on the bike with your full gear, put both feet on footpegs, adjust with a friend's help, and note the new measure as M2.
  4. Calculate sag by subtracting M2 from M1 rear fender.
  5. If you're heavier, decrease sag by tightening the lock axle nut clockwise; if you're lighter, increase sag by loosening the rear axle nut anti-clockwise.

Step 3: Adjust Compression and Rebound Damping

Now that your sag is set, you can move on to adjusting the compression and rebound damping, which helps control the bike's suspension movement over bumps and jumps.

Compression Damping: Responsible for controlling the bike's movement during compression. It controls how fast the suspension compresses under load.


  • Heavier riders: Increase compression damping (usually means turning the adjuster clockwise)
  • Lighter riders: Decrease compression damping (usually means turning the adjuster anti-clockwise)

Rebound Damping: Controls how quickly the suspension rebounds after compressing.


  • Heavier riders: Increase rebound damping (turn the adjuster clockwise)
  • Lighter riders: Decrease rebound damping (turn the adjuster anti-clockwise)

Step 4: Fine-Tune Preload Settings

Once your sag is adjusted and your damping is dialed in, you may need to make adjustments to your preload settings. Preload refers to the correct spring rate tension already applied to the bike's suspension.


  • Heavier riders: Increase preload (tighten the preload adjusters)
  • Lighter riders: Decrease preload (loosen the preload adjusters)

Step 5: Test and Iterate Until You Find the Perfect Balance

After adjusting the bike's suspension according to your weight, it's crucial to test everything on the track or trail. Ride your dirt bike through various conditions, pay attention to how it feels, and take note of any issues or discomfort.

Importance of Proper Suspension Adjustment

Adjusting your dirt bike suspension to your own weight is crucial to enhance comfort, handling, and safety. Following these guidelines and recommendations can significantly improve your off-road experiences and help you ride confidently.

Enhanced Comfort and Ride Quality

A key aspect of enjoying your dirt bike riding experience is making sure your suspension is properly adjusted for your weight. When your suspension is tuned to your specific needs, you'll experience increased comfort and ride quality.

Finding the right balance between front and rear suspension is essential to ensure a smooth ride. Not only will a well-adjusted suspension improve your overall riding experience, but it will also allow you to tackle various types of terrain easily.

When it comes to dirt bike suspension, rider weight and riding style play a significant role in determining the appropriate adjustments.

Use the table below as a rough guide to setting up your dirt bike for optimal performance:

Under 100 lbs Soft Preload & Rebound Soft Preload & Rebound
100-150 lbs Medium Preload & Rebound Medium Preload & Rebound
Over 150 lbs Firm Preload & Rebound Firm Preload & Rebound

Improved Handling and Control

Another essential aspect of proper suspension adjustment is the improvement in handling and control. When your suspension is well-balanced, it allows you to maneuver your dirt bike with precision, increasing your confidence and ability to tackle challenging trails. Fine suspension tuning your bike's sag helps you achieve optimal performance on rough terrain and riding conditions.

Enhanced Safety and Reduced Fatigue

Proper suspension adjustment contributes to a better riding experience and performance and enhances your safety on the trails. Correctly adjusted suspension allows equal weight distribution across the bike, providing better stability during cornering and braking. As a result, you'll be less likely to face dangerous situations, ultimately reducing the risk of accidents.

Better suspension settings also contribute to reduced rider fatigue by absorbing shocks and impact effectively, allowing you to ride longer and enjoy your time on the trails.

Key safety benefits include:

  • Improved stability during cornering and braking
  • Reduced risk of accidents
  • Less fatigue on long rides

Factors to Consider for Weight-Based Suspension Adjustment

Keep in mind that suspension setup is a personal preference, and adjustments will vary from rider to rider. Pay attention to how your dirt bike feels, and make gradual changes to find the most comfortable configuration for your weight.

Measuring Your Weight Accurately

It is essential to measure your weight accurately before making any adjustments to your dirt bike's suspension. I recommend using a digital scale, which is the most accurate way to get your precise weight.

To prevent inconsistencies, weigh yourself wearing your riding gear or account for the additional weight of your riding gear when measuring your weight. Having the correct weight will enable you to adjust your dirt bike's suspension for a more comfortable ride.

Understanding Sag and Its Significance

Sag is a crucial aspect of dirt bike suspension that directly affects the bike's handling and stability. It refers to the amount the suspension compresses under the bike's weight, the rider's weight, and the combined weight of both.

There are two types of sag measurements:

  1. Free Sag: The suspension's compression amount when only the bike's weight is applied.
  2. Rider Sag: The compression amount of the suspension when the combined weight of the bike and rider is applied.

Evaluating Suspension Components and Settings

In addition to sag, there are other components and settings of your dirt bike suspension to evaluate before making any adjustments to suit your weight:

  • Springs: Dirt bike suspension systems typically use coil springs or air springs. Coil springs are available at different rates to accommodate various rider weights. So, make sure to choose the correct spring rate for your weight.
  • Damping: Damping refers to the control over the low-speed compression at which your suspension compresses and rebounds. It is crucial for maintaining balance and stability on your dirt bike. Two types of high-speed suspension damping adjustments are fork compression damping and rebound damping.

Common Suspension Adjustment Mistakes to Avoid

When adjusting your dirt bike suspension to your weight, it's essential to avoid common mistakes that can negatively impact your ride.

Neglecting Proper Weight Measurement

One of the most critical steps in adjusting your dirt bike suspension is accurately measuring your weight. This means considering your body weight and the gear you'll be wearing while riding. Failing to account for this extra weight can lead to improperly adjusted suspension, resulting in poor handling, discomfort, and reduced performance.

To avoid this mistake, ensure that you:

  • Weigh yourself in your riding gear, including a helmet, boots, and any other equipment you'll be wearing while riding.
  • Remember to account for any luggage or other additional weight you may carry on your bike during your rides.

Overlooking Sag Setup Importance

Another common mistake is overlooking the importance of setting up your sag. Sag is the measure of how much your suspension compresses under your weight, and it plays a crucial role in the overall performance of your dirt bike.

To set up your sag correctly, you should:

  • Determine your desired rider sag, which is the amount of suspension compression when you are sitting on the bike with all your riding gear on.
  • Measure your static sag, which is the suspension compression caused by the bike's weight.
  • Adjust your rear spring preload ring adjuster to achieve the correct rider sag within the recommended range by your bike's manufacturer.

Making Hasty and Drastic Changes

Lastly, avoid making hasty and drastic changes to your dirt bike suspension settings. Making significant adjustments without understanding the consequences can lead to a dangerous and uncomfortable ride. Instead, approach your suspension adjustment with patience and a methodical approach.

Consider the following tips when adjusting your suspension:

  • Start by making small, incremental adjustments to your suspension settings. Record each change and observe how it affects your ride.
