Get Low: A Guide to Harley Davidson Lowers and Why You Need Them

What are lowers on a Harley

Lowers, also known as fork lowers or triple trees, are a crucial component of a Harley-Davidson motorcycle's front suspension system.

They are located at the base of the front fork tubes and serve as the connection point between the forks and the motorcycle's frame.

The primary purpose of lowers is to provide a secure and sturdy mounting point for the front fork assembly, allowing it to pivot smoothly and absorb impacts from the road.

They play a vital role in the handling and stability of the motorcycle, as they help distribute the forces from the front suspension evenly across the frame.

Lowers consist of two main parts: the upper and lower triple trees.

The upper triple tree is connected to the handlebar stem, while the lower triple tree is attached to the front fork tubes.

Together, these components form a sturdy and rigid structure that ensures precise steering and control over the motorcycle's front end.

Types of Lowers on Harleys

Lowers on Harley-Davidson motorcycles come in various styles and materials, catering to different rider preferences and customization needs. The most common types include:

Stretched Lowers

These lowers extend the length of the motorcycle's frame, creating a longer and more stretched-out appearance. They are popular among riders who desire a more aggressive and raked-out stance for their Harleys.

Extended Lowers

Similar to stretched lowers, extended lowers increase the overall length of the frame, but to a lesser degree. They provide a subtle yet noticeable elongated look without going to the extreme of stretched lowers.

Steel Lowers

Crafted from high-quality steel, these lowers offer durability and strength. Steel lowers are often chosen for their rugged and classic appearance, as well as their ability to withstand the rigors of long-distance riding.

Aluminum Lowers

Lightweight and corrosion-resistant, aluminum lowers are a popular choice for riders seeking a sleek and modern look. They can also contribute to improved performance by reducing the overall weight of the motorcycle.

Billet lowers are precision-machined from a solid block of aluminum or other metal, resulting in a high-quality and visually striking component. These lowers are often intricately designed and are popular among riders who value intricate detailing and craftsmanship.

Bobbed Lowers

Bobbed lowers are shorter than stock lowers, giving the motorcycle a more compact and aggressive appearance. They are often paired with other bobber-style modifications for a minimalist and stripped-down look.

Factory Lowers vs Aftermarket Lowers

When it comes to lowers for your Harley-Davidson motorcycle, you have two main options: factory (or OEM) lowers and aftermarket lowers.

Factory lowers, also known as OEM (Original Equipment Manufacturer) lowers, are designed and manufactured by Harley-Davidson themselves.

These lowers are built to the exact specifications and tolerances required for each specific Harley model. They are designed to work seamlessly with the rest of the motorcycle's components, ensuring a perfect fit and optimal performance.

One of the main advantages of factory lowers is the assurance of quality and reliability.

Harley-Davidson has strict quality control measures in place, and their lowers are rigorously tested to meet the highest standards.

Additionally, factory lowers are covered by the manufacturer's warranty, providing peace of mind in case of any defects or issues.

However, factory lowers can be more expensive than aftermarket options, and they may offer fewer customization possibilities.

Harley-Davidson typically produces lowers in a limited range of styles and finishes, which may not align with every rider's aesthetic preferences.

On the other hand, aftermarket lowers are produced by third-party manufacturers and are designed to fit specific Harley models.

These lowers often come in a wide variety of styles, finishes, and materials, allowing riders to truly personalize the look of their motorcycles.

Aftermarket lowers can be more affordable than factory options, making them an attractive choice for riders on a budget.

Ultimately, the choice between factory and aftermarket lowers comes down to personal preferences, budget, and priorities.

Factory lowers offer the assurance of quality and seamless integration, while aftermarket lowers provide more customization options and potential cost savings.

Lowers and Motorcycle Handling

Lowers on a Harley-Davidson motorcycle play a crucial role in influencing the bike's handling characteristics.

These components, which extend below the frame, impact several aspects of the riding experience, including steering, balance, and turning radius.

Lowers primarily affect the motorcycle's rake and trail, two key factors that determine how the bike handles.

The rake refers to the angle of the fork tubes relative to the ground, while the trail is the horizontal distance between the point where the steering axis intersects the ground and the center of the front tire's contact patch.

By lowering the bike's overall height, lowers effectively decrease the rake angle and increase the trail measurement.

This configuration results in improved straight-line stability and a more responsive steering feel. However, it also reduces the turning radius, making it slightly more challenging to execute tight turns or maneuver in confined spaces.

Furthermore, lowers can influence the bike's center of gravity.

By lowering the motorcycle's overall height, the center of gravity is brought closer to the ground, enhancing stability and reducing the likelihood of tipping over during low-speed maneuvers or while stopped.

It's important to note that the extent to which lowers affect handling characteristics depends on the specific design and dimensions of the components.

Significant changes in rake, trail, and overall height can have a substantial impact on the bike's handling, while more subtle modifications may result in more nuanced differences.

When considering lowers for a Harley-Davidson motorcycle, it's essential to strike a balance between the desired handling characteristics and the rider's preferences and riding style.

Some riders may prioritize agility and tight turning capabilities, while others may value increased straight-line stability and a more planted feel on the road.
