More Stability. More Control. More Confidence.

Dynas are built to be ridden.

And when you're pushing yours harder—whether you're carving through the canyons, accelerating through rough pavement, or putting down serious highway miles—keeping the front end composed matters.

The GPR V5S Steering Stabilizer for Harley-Davidson Dyna adds adjustable steering damping to help control unwanted handlebar movement and give your bike a more planted, predictable feel.

Race-proven technology. Fully adjustable. Clean, bolt-on installation.

Because a performance Dyna should handle like one.

Race-Proven GPR V5S Technology

The GPR V5S is the fifth generation of GPR's Harley-Davidson steering stabilizer system.

Since its debut in 2007, GPR's stabilizer technology has become a favorite among amateur and professional road racers.

The Harley application brings that performance-focused technology to the Dyna platform with a system designed specifically around the motorcycle—not a universal damper adapted to fit.

What Does a Steering Stabilizer Do on a Dyna?

A steering stabilizer adds controlled resistance to sudden or unwanted steering movement while still allowing normal rider steering input.

For performance Dyna riders, that can help create a more composed front-end feel during:

Aggressive acceleration
Higher-speed riding
Canyon and backroad riding
Rough or uneven pavement
Quick steering inputs
Performance-oriented riding

It's another layer of control between you, the bars, and the road.

Adjust Your Damping on the Fly

Different roads call for different setups.

The GPR V5S features a large, highly visible adjustment dial, allowing you to quickly change the damping level to match your riding conditions and preferences.

Want additional steering resistance? Dial it up.

Want a lighter steering feel? Dial it back.

The control is right at your fingertips.

Patented Pin-Less Mounting System

One of the things that separates the GPR system from traditional steering dampers is its clean mounting design.

The V5S utilizes GPR's patented pin-less mounting system, eliminating the bulky appearance of many conventional stabilizer installations.

The result is a functional performance upgrade that looks like it belongs on the bike.

Billet Aluminum Top Clamp

Rather than relying on the traditional base-plate style mounting system commonly used on sportbike applications, the Harley-Davidson setup incorporates a beautifully machined billet aluminum top clamp.

This creates a cleaner, more integrated appearance that's equally at home on a stock Dyna or a fully built club-style bike.

The Harley-Davidson Dyna application includes:

GPR V5S steering damper
Machined billet aluminum top clamp
Machined aluminum frame mounts
Black anodized steel hardware

100% Bolt-On Installation

No cutting. No welding. No drilling into your original equipment.

The GPR Steering Stabilizer is engineered as a bolt-on Harley performance upgrade, allowing you to improve steering control without permanently modifying your motorcycle.

Choose Your Stabilizer Color

Available damper colors include:

Black
Red
Blue
Gold

Choose something subtle—or make the stabilizer part of the build.

Why Add a Steering Stabilizer to Your Dyna?

Horsepower gets attention. Handling makes the motorcycle.

If you've already upgraded your Dyna with better suspension, bars, risers, brakes, tires, or engine performance, a steering stabilizer is another way to refine the way the bike responds when you start riding harder.

The GPR V5S Steering Stabilizer combines adjustable steering damping with a clean, Dyna-specific installation for riders who care about how their motorcycle performs—not just how it looks.

More Power Deserves More Control.

Your Dyna doesn't need to be a race bike to benefit from race-developed technology.

Upgrade your front end with the GPR V5S and add another level of control, stability, and confidence to your performance build.
