Frequently Asked Questions

What does Speed Adaptive Valving (SAV) do?

SAV adjusts damping in real-time based on road speed and conditions, maintaining ride quality on both smooth highways and rough surfaces.

Do I need special tools to adjust the preload?

No — the spring preload cap is hand-adjustable without tools, letting you dial in stiffness for your load and riding preference.

What is the Internal Floating Piston (IFP)?

The IFP separates the damping fluid from the pressurized gas chamber, stabilizing performance and preventing fade over time.

Are these a direct bolt-on replacement?

Verify your current shock length and mounting points with your motorcycle's manual before ordering to ensure fitment.
