Get ready to transform your ride from a bone-jarring experience to a smooth, flowing cruise!

Why Upgrade Your Harley Trike Suspension?

So, why bother with a Harley trike suspension upgrade in the first place? Well, the stock suspension on many trikes, especially older models, is often designed with cost-effectiveness in mind. This can mean a stiff ride that transmits every bump and imperfection in the road directly to your backside. Ouch! Not exactly the kind of comfort you're looking for on those long highway hauls or scenic weekend rides. The stock suspension might also struggle with handling. Because trikes have a different center of gravity compared to two-wheeled bikes, good suspension is super critical for stability and control. A poor suspension setup can lead to a feeling of instability, especially during cornering or when encountering uneven road surfaces.

Beyond comfort and handling, upgrading your suspension can also contribute to safety. Improved suspension can give you better control of your trike, especially in emergency situations. It allows the tires to maintain better contact with the road, improving braking performance and overall stability. A well-tuned suspension setup reduces the chance of bottoming out, which occurs when the suspension compresses fully and hits its limit. This can damage components and drastically reduce control. Another factor to consider is the weight of your trike. Trikes, with their added components and typically larger riders or passengers, often carry a significant load. The stock suspension might not be up to the task of handling this extra weight effectively. This can lead to sagging, reduced ride height, and a generally uncomfortable experience. By upgrading to a more robust suspension system, you're essentially providing your trike with the support it needs to handle the load properly. Furthermore, consider your riding style and the types of roads you typically ride on. If you're someone who enjoys long-distance touring, comfort is paramount. A softer, more compliant suspension system will absorb bumps and vibrations, reducing fatigue and making your rides more enjoyable. If you tend to ride on rough roads or encounter potholes regularly, a suspension upgrade is practically a must-have. So, whether it's for comfort, handling, safety, or just to make your trike look and perform its best, a suspension upgrade is a smart move. Let's get into the nitty-gritty of the upgrades.

Types of Harley Trike Suspension Upgrades

Alright, let's explore the main types of Harley trike suspension upgrades you can choose from. Each type offers a unique set of benefits, so the best choice for you will depend on your specific needs and riding style. We will discuss about rear suspension upgrades, front suspension upgrades, and additional suspension upgrades.

Rear Suspension Upgrades

Air Ride Suspension:

Air ride systems are the ultimate in adjustability and comfort, guys. They use air springs (also known as air bags) that can be inflated or deflated to change the ride height and stiffness of your suspension. The main advantage of air ride is the ability to fine-tune your ride for different conditions. You can raise your trike for better ground clearance on rough roads, or lower it for a sleek look. The adjustability also means you can compensate for passenger weight or cargo. Air ride systems often include a compressor, air tank, and control system. This lets you adjust the suspension on the fly, with some systems even offering pre-set ride heights. But hey, it comes with a higher price tag compared to other options, and the installation can be more complex. Maintenance is also something to be aware of, as you'll need to check for leaks and maintain the air system. However, for those who value ultimate comfort and adjustability, air ride is the way to go.

Coilover Shocks:

Coilover shocks, or coil-over shocks, are a popular upgrade for improving both ride quality and handling. Unlike the stock shocks, which are often basic and lack adjustability, coilovers typically offer adjustable damping and preload. Damping controls how quickly the suspension compresses and rebounds, allowing you to fine-tune the ride to your liking. Preload adjusts the ride height and initial stiffness of the suspension. Coilovers are generally more affordable than air ride systems. They are also relatively easy to install. However, they are not as adjustable as air ride. Once you set them up, you're pretty much locked in until you make further adjustments. Coilover systems can provide a significant improvement in both ride comfort and handling, making them a great choice for those who want a noticeable upgrade without breaking the bank.

Aftermarket Shocks:

Upgrading the rear shocks is one of the most common and accessible suspension upgrades. Aftermarket shocks are available from a variety of manufacturers and offer a range of improvements over the stock shocks. You can find shocks with adjustable damping, which lets you dial in the ride quality to your preferences. Some shocks also offer adjustable preload, which lets you fine-tune the ride height and stiffness. The benefits of aftermarket shocks are improved ride quality, better handling, and increased load capacity. The installation process is usually straightforward. However, the level of improvement you get will depend on the quality of the shocks you choose. Be sure to select shocks that are specifically designed for trikes and that match your riding style and needs.

Front Suspension Upgrades

Fork Springs:

Upgrading the fork springs is a relatively simple and cost-effective way to improve the front suspension of your trike. Stock fork springs are often designed for a wide range of riders and riding conditions, which can mean they are not perfectly optimized for your needs. Aftermarket fork springs are available in various rates, allowing you to choose springs that match your weight and riding style. Heavier riders will benefit from stiffer springs, while lighter riders might prefer softer springs. The benefits of upgraded fork springs are improved handling, reduced diving under braking, and a more controlled ride. The installation is typically straightforward and can be done at home with basic tools. However, you'll need to remove the fork tubes, so it's best to have some mechanical experience. The improvement will primarily be in the handling and stability of the front end.

Cartridge Kits:

Cartridge kits are a more comprehensive upgrade for the front forks. These kits replace the internal components of the forks, including the damping rods and springs. They typically include adjustable damping, allowing you to fine-tune the compression and rebound of the forks. The benefits of cartridge kits are significant improvements in handling, ride quality, and overall performance. They provide a more controlled and compliant ride compared to stock forks. The installation is more complex than a fork spring upgrade and often requires professional installation. Cartridge kits are a more expensive upgrade, but they provide a substantial improvement in the front suspension performance.

Additional Suspension Upgrades

Trike Kits with Independent Rear Suspension (IRS):

If you're really serious about upgrading your trike's suspension, consider a trike kit that features independent rear suspension (IRS). IRS systems allow each rear wheel to move independently, which dramatically improves ride quality and handling. This is a significant upgrade from the solid axle rear suspension found on many trikes. The benefits of IRS are a smoother ride, better handling, and improved traction. The installation is more complex and requires significant modifications to the frame. The cost is also much higher than other suspension upgrades. However, the results are a substantial improvement in both comfort and performance. If you have the budget and are looking for the best possible ride, an IRS trike kit is the way to go.

Swingarms and Custom Setups:

For those seeking a truly unique and high-performance setup, you can explore custom swingarms and suspension configurations. These can involve everything from custom-built swingarms to specialized shocks and linkages. The benefits are a highly customized suspension system tailored to your specific needs and riding style. The installation requires significant fabrication and expertise, often involving a professional mechanic or custom bike builder. This is the most expensive and time-consuming option. It's best suited for experienced riders or those who prioritize maximum performance and customization.

Choosing the Right Suspension Upgrade for Your Harley Trike

Okay, guys, so you know the different types of upgrades now. But how do you choose the right one for your trike? Here's what you need to consider. First, think about your riding style. Do you prioritize comfort or performance? Do you do long-distance touring, or do you enjoy spirited rides? If comfort is your main concern, air ride or aftermarket shocks with adjustable damping are great options. If you're looking for improved handling, coilover shocks or cartridge kits are a good choice. Second, think about your budget. Suspension upgrades can range in price from a few hundred dollars to several thousand. Decide how much you're willing to spend and then explore the options within that range. Third, consider the complexity of installation. Some upgrades can be installed at home with basic tools, while others require professional installation. If you're not comfortable working on your trike, factor in the cost of labor. Next, consider your weight and load. Heavier riders or those who often carry passengers or cargo may need heavier-duty suspension components. Make sure the upgrades you choose are rated to handle the weight of your trike and its load. Then, read reviews and do your research. Talk to other trike owners, read online reviews, and compare different products before making a purchase. Finally, think about the brand and reputation of the manufacturer. Choose reputable brands known for quality and reliability. Do not be afraid to seek advice from a professional mechanic if you're unsure which upgrade is right for you. They can assess your specific needs and recommend the best options.
