What Is a Harley-Davidson Air Suspension Chart?

The Harley-Davidson Air Suspension Chart is a reference guide that shows the recommended air pressure and ride height settings for different riding conditions. Think of it as a map for your suspension system. It tells you exactly what settings to use based on how much weight your bike is carrying.

Most Harley-Davidson models that come with air suspension include a chart in the owner’s manual. You can also find updated versions online from Harley-Davidson or aftermarket parts makers. The chart usually lists settings for three main situations:

• Solo riding with no extra weight
• Rider and passenger with normal luggage
• Heavy load with a full saddlebag and trunk setup

Each setting includes a recommended air pressure level measured in PSI (pounds per square inch). The chart also shows the target ride height. Ride height is the distance between the ground and the lowest point of the bike. Getting this right is key to a smooth and safe ride.

Why the Chart Matters for Air Ride Suspension

Air ride suspension systems use air springs instead of traditional coil springs. These air springs are flexible and respond well to changes in air pressure. When you add air, the suspension rises. When you let air out, it lowers. This makes the Harley-Davidson Air Suspension Chart so useful. It gives you the exact PSI numbers you need for each riding scenario.

Without the chart, you would be guessing. Guessing can lead to a poor ride. Your bike might sit too low or too high. It might feel bouncy or stiff. The chart removes all the guesswork. It gives you clear numbers that are tested and approved by Harley-Davidson engineers.

Why You Need an Air Suspension Adjustment Chart

Riding a Harley with the wrong suspension settings can ruin your experience. A bike that sits too low can scrape on bumps. A bike that sits too high can feel unstable in turns. The Harley-Davidson Air Suspension Chart helps you avoid all of these problems.

Here are the main reasons you need this chart:

• Comfort: The right settings make long rides much more comfortable. Your body absorbs less vibration from the road.
• Safety: Proper ride height improves handling and braking. You stay in control on wet roads, curves, and rough terrain.
• Load Balancing: When you add a passenger or heavy bags, the rear of the bike sags. The chart helps you level things out.
• Protect Your Bike: Wrong settings can damage your shocks, air springs, and frame over time. The chart keeps everything within safe limits.
• Save Time and Money: You can make adjustments at home instead of paying a mechanic to do it.

Many riders buy aftermarket air suspension kits from brands like Progressive Suspension or Arnott. These kits often come with their own adjustment charts. But the factory Harley-Davidson Air Suspension Chart remains the gold standard. It is designed specifically for your bike model and engine type.

How Suspension Sag Affects Your Ride

Suspension sag is the amount the rear end drops when you sit on the bike. Too much sag means the bike sits too low. Too little sag means the suspension is too stiff. The Harley-Davidson Air Suspension Chart helps you find the sweet spot. Most riders aim for about one inch of sag when sitting on the bike with normal gear.

You can measure sag with a simple tape measure. Just measure the distance from the rear axle to a fixed point on the fender. Then sit on the bike and measure again. The difference is your sag. Compare this to the chart recommendations and adjust the air pressure accordingly.

How to Read and Use the Air Suspension Chart

Reading the Harley-Davidson Air Suspension Chart is easier than you might think. The chart is usually laid out in a simple table format. Each row represents a different riding condition. Each column shows the air pressure and ride height for that condition.

Here is what a typical chart entry looks like:

• Condition: Solo rider, no luggage
• Recommended PSI: 7 PSI
• Target Ride Height: 5.5 inches from the ground to the lowest point of the exhaust

To use the chart, first figure out your riding condition. Are you riding alone or with a passenger? Do you have saddlebags and a trunk? Match your situation to the right row on the chart. Then set your air pressure to the recommended PSI. Finally, check your ride height and make small adjustments if needed.

Tools You Will Need

Before you start, gather these tools:

• A motorcycle air pump or compressor with a pressure gauge
• A tape measure or ruler
• The Harley-Davidson Air Suspension Chart for your specific model
• A pen and notebook to track your settings

Most Harley-Davidson models use a small air compressor built into the bike to add or release air. You can also buy an aftermarket inflation kit if your bike does not have one. The process is simple. Just connect the pump, add air to reach the target PSI, and check the ride height.

Quick Tips for Reading the Chart

• Always check the chart for your specific model year. Settings can change between years.
• Make adjustments when the suspension is cold. Riding heats up the air and changes the pressure.
• Write down your settings after each ride so you can repeat them easily.
• If you are between two PSI values, start with the lower number and add air slowly.

Common Harley-Davidson Air Suspension Models and Settings

Different Harley-Davidson models use different air suspension systems. The Harley-Davidson Air Suspension Chart varies by model. Here are some of the most common models and their general settings.

Softail Models

Softail models like the Softail Standard and Softail Slim use rear air suspension. These bikes have a classic look but still offer modern comfort. The factory chart usually recommends lower PSI for solo riders and higher PSI when carrying a passenger. Ride height on Softails is easy to adjust because the rear air spring is accessible.

Touring Models

Touring bikes like the Road King and Street Glide come with air suspension on both the front and rear. These bikes are designed for long-distance comfort. The Harley-Davidson Air Suspension Chart for touring models includes more settings because they carry more gear. Front fork air pressure is just as important as rear spring pressure. Always check both sides when making adjustments.

Dyna Models

Dyna models like the Fat Bob and Street Bob often have rear air suspension. These bikes are popular for custom builds. Many riders add aftermarket air suspension kits for a more aggressive look. The factory chart still works as a starting point, but you may want to fine-tune the settings for your style.

CVO and High-Performance Models

CVO (Custom Vehicle Operations) models come with premium suspension systems. These bikes often have electronic suspension adjustment. The Harley-Davidson Air Suspension Chart for CVO models may include electronic presets. You can switch between settings with the push of a button on the handlebar.

Comparison Table: Common Model Settings

Model Type	Solo PSI	Passenger PSI	Heavy Load PSI
Softail	7 PSI	9 PSI	11 PSI
Touring	8 PSI	10 PSI	12 PSI
Dyna	6 PSI	8 PSI	10 PSI
CVO	Electronic	Electronic	Electronic

Note: These values are general examples. Always refer to your specific model’s Harley-Davidson Air Suspension Chart for exact numbers. Settings can vary based on engine size, year, and factory options.

Step-by-Step Guide to Adjusting Your Air Suspension

Now that you understand the chart, let’s walk through the actual adjustment process. Follow these steps to get the best results from your Harley-Davidson Air Suspension Chart.

Step 1: Park on a Level Surface

Always start by parking your bike on a flat, hard surface. A garage floor or driveway works great. Do not adjust your suspension on a slope. The bike needs to be level for accurate measurements.

Step 2: Measure Your Current Ride Height

Use a tape measure to check the distance from the ground to the lowest point of the bike. Write this number down. This is your baseline. It helps you see how much you need to adjust.

Step 3: Check the Chart for Your Condition

Look at the Harley-Davidson Air Suspension Chart and find the row that matches your riding situation. Note the recommended PSI and target ride height.

Step 4: Connect Your Air Pump

Attach your air pump or compressor to the air valve on the suspension. Most Harley-Davidson models have the valve near the rear wheel or under the seat. Add air slowly and check the pressure gauge often.

Step 5: Adjust the PSI

Add or release air to reach the recommended PSI from the chart. Go slowly. Small changes make a big difference. If you add too much air, you can always let some out.

Step 6: Recheck the Ride Height

After adjusting the air pressure, measure the ride height again. Compare it to the target height from the chart. Make small adjustments until you hit the mark.

Step 7: Take a Test Ride

Once you have the right settings, take a short test ride. Pay attention to how the bike feels. Does it ride smooth? Does it handle well in turns? If something feels off, make small tweaks and test again.

Quick Tips for the Adjustment Process

• Adjust your suspension every time your riding conditions change.
• Keep a log of your settings for different scenarios.
• Never exceed the maximum PSI listed on the chart or in your owner’s manual.
• If your bike has electronic suspension, use the handlebar controls for fine-tuning.

Troubleshooting Common Air Suspension Issues

Even with the right Harley-Davidson Air Suspension Chart, you may run into issues from time to time. Here are the most common problems and how to fix them.

Rear End Sags Too Much

If your rear end sags when you add a passenger or luggage, you need more air pressure. Check the chart for the correct PSI for your load. Add air slowly until the ride height matches the target. If the sagging continues, you may have a leak in the air spring. Inspect the air bag for cracks or damage.

Bike Rides Too High and Bouncy

If your bike feels too bouncy or sits too high, you have too much air. Let some air out until the ride height drops to the recommended level. A bike that is too high can feel unstable, especially at low speeds and in parking lots.

Air Compressor Runs Constantly

If your air compressor keeps running, there may be a leak in the system. Check all air lines and fittings for cracks or loose connections. A small leak can cause the compressor to work overtime. This can burn out the compressor motor over time.

Uneven Ride Height

If one side of the bike sits lower than the other, the air spring on that side may be failing. This is a common issue with older air suspension systems. Inspect both air springs and replace any that show signs of wear or damage.

When to Seek Professional Help

Some suspension problems are best handled by a trained mechanic. If you notice oil leaking from your shocks, strange noises when riding, or if the bike pulls to one side, get it checked. A professional can diagnose issues that go beyond simple air pressure adjustments.

Maintenance Tips for Long-Lasting Suspension

Your air suspension system needs regular care to perform its best. Here are some simple maintenance tips that every Harley owner should follow.

• Check air pressure weekly: Air springs can lose pressure over time. A quick weekly check keeps your ride consistent.
• Inspect air bags regularly: Look for cracks, tears, or bulges in the air bags. Replace them if you see any damage.
• Keep the compressor clean: Dust and debris can clog the compressor. Wipe it down and keep the area around it clear.
• Lubricate fittings: Apply a small amount of silicone lubricant to air line fittings to prevent leaks.
• Follow the Harley-Davidson Air Suspension Chart: Always use the chart as your guide. Do not guess or improvise with air pressure settings.

Good maintenance habits extend the life of your suspension system. They also keep your ride smooth and safe mile after mile. A well-maintained air suspension system can last for many years with proper care.
