The new MXT Lucky System (Lucky) is the newest advancement for WP 4CS forks. The Lucky system is the result of innovative engineering and a commitment to bring riders the best value in the suspension market. Lucky Nichols, a professional suspension tuner, was discussing some long range fork projects with Jeremy Wilkey, and suggested that the existing MXT 4CS Asymmetrical kit could be “repackaged” with the new cartridges and hardware that MXT is currently producing. Major enhancements include:

  • Over a pound lighter than stock 4CS forks
  • Increased cartridge volume to a 22mm diameter
  • A redesigned Huck Valve
  • New compression and rebound adjusters
  • Quality machining to reduce friction
  • DIY: Drop in ready system

As a pioneer of 4CS solutions, MXT has made many improvements to the stock system by building on the existing strengths. MXT continues to refine the 4CS product using solid in-house engineering based on rider feedback. Attention was given to make the 4CS forks “plush” while maintaining the control required to ride aggressively.

The Lucky forks exhibit better handlebar feel, steering response, and traction since they are lighter than stock. An increase in cartridge volume provides more control and support through the middle of the stroke. As an example, riders also notice the inherent stiffness of a stock 4CS fork. This is due to a valving set-up that requires stiff settings to control large fork movements, which produce frictional effects and forces created by cartridge pressurization. With the Lucky, the new 3 port mid-valve piston can be adjusted to improve the initial feel and reaction. The Lucky also includes the proven Huck Valve, designed to increase volume while allowing for additional pressure transfer parallel to the system. New adjusters were added to simplify tuning for the rider. Finally, attention was given to better machined bearings and pressurized seal surfaces to reduce friction.

Traditional stock bottoming control system is limited in that it can’t manage multiple speeds or accelerations inside its travel. Stock systems can be adjusted to provide good control for either low or high-speed bottoming, but doing so limits the ability to absorb the other. The MXT Huck Valve manages the limitations of typical bottoming control systems. The MXT Huck Valve has speed sensitive bottoming control, by incorporating a pressure sensitive valving mechanism. This allows for both high entry speeds and low entry speeds effectively. MXT Huck Valve equipped forks allows the set-up to be plusher while not sacrificing the overall control of the fork.

Prototypes were made, dyno tested, and put to the track for real world testing. After excellent results from a diverse group of riders on various terrains, the Lucky 4CS System entered production and is ready to ship today.
