Product Description

MXT A48-R Kit (WP AER48 Fork Upgrade)

  • MXT A48-R fork cap introduces an additional high pressure air chamber inside the WP AER48 Air Cartridge
  • The addition of a compensating high pressure volume above the main pressure region results in a smoother pressure rise (less progressive) as the fork compresses
  • This is achieved by having a "floating piston" separate the main pressure region and the new high pressure region
  • As the pressure inside the main pressure region begins to increase during fork compression, near the mid stroke point of fork travel the main pressure region psi rises above the new high pressure regions psi thus moving the "floating piston" creating additional volume for the main pressure region (Slowing down the hyper progressive nature of the fork)
  • Near the end of the fork stroke the floating piston stops moving (creating additional volume) resulting in a dramatic pressure increase which is perfect for excellent bottoming control
  • Also allows for tuning of the "Low Pressure" outer fork chamber area similar to the Showa TAC fork
  • Allows for tuning of balance spring pressure via o-ring volume management
  • MXT AER48 Works Midvalve Assembly
  • Replaces the OEM WP plastic midvalve piston
    • OEM piston is very limited in effective tuning via shims
  • Features the works inspired leaf spring midvalve design
  • Divides shim deflection into three tune-able regions
    • Drastically improves shim fatigue service life
  • Improved oil flow for much improve fork feel thru the entire stroke
  • Incorporates a rebound separator check valve that isolates the rebound function from the MV compression function
  • Fits all KTM and Husky models with WP AER48 Fork
  • Motocross, Supercross, Arenacross, Enduro, Off-Road, GNCC, FreeRiding
  • The MXT A48-R Kit includes MXT A48-R Fork Cap, MXT Bones Air Fill Valve, and MXT AER48 Works Midvalve Piston Assembly

 

The Result
  By dividing the air compression region of WP AER48 fork into two regions that adjust volume via pressure allows for a less progressive air pressure build up through the forks travel until the very end when its needed.  A smoother increase in air pressure build up provides a similar feel to metal coil fork spring without the addition of the weight or rubbing friction associated with a fork spring.  Essentially this is how WP and Showa should have designed their air forks.
