Arnott Motorcycle Air Suspension is your #1 source for motorcycle fork cartridges. Our performance fork cartridges are tuned to work in unison with JRi shocks to help provide a smooth and controlled ride. We currently carry fork cartridges for Harley-Davidson and Indian motorcycles. These kits will replace all of the fork internals and will be constructed of all aluminum, aircraft grade parts, with some parts offering a Teflon coating to eliminate friction along the spring. The piston design allows for dynamic low-speed and high-speed control to help improve front brake diving, stability, cornering, and bottoming control. Each kit will include Hyperco fork springs and an easy spring reload adjusting perch tool.
