Motorcycle Fork Adjustable Replacement Cartridge Kits

Fork Cartridge Kits

Upgrade your motorcycle forks with precision cartridge kits to improve damping, comfort and control across road, track and off-road riding. Kits include mechanical clicker systems, air-to-coil conversions and ESA-compatible plug-in solutions for modern forks.

Precision damping, tunability and long-term serviceability

  • Consistent compression & rebound control through the full fork stroke
  • Reduced harshness, improved traction and reduced brake dive
  • Clicker-adjustable and ESA-compatible options for fine tuning
  • Rebuildable, revalvable internals and correct spring rates for lasting performance

Recommended Pairings

Consider matching upgrades with Suspension Tools and suspension oil for correct setup. For kit types and fitment see Mechanical fork cartridges, Air-to-coil conversions and ESA-compatible cartridges. Professional fitting and setup advice is available via our dealer finder, and oils and consumables at Suspension Oils. Contact our specialists at Contact Us.
