MXT Blackjack Cartridge System

MXT Blackjack Closed Cartridge System

In the continuation of our pursuit of the best performing front suspension, we focused on developing a close chambered version of our Lucky cartridge systems. Using 
the best materials available, the Blackjack’s unique design surpasses the limitations found in other closed chamber designs.

A large diameter spring-charged ICS piston operates in a Kashima coated tank to create optimal pressure balance and the lowest friction values possible, while 
ensuring 1:1 self-regulation of internal volume and a hydraulic spring characteristic that is not possible with gas charged designs. 

The 25mm cartridge tube creates a piston area and swept oil volume that produces great speed sensitive properties and allows for a wide range of damping coefficients. The unique cir-clip retained compression adjuster reduces mass and has the convenience of 360 degree repositioning. Highly developed mid-valve 
design allows for maximum tuning and longevity.  

The Black Jack is the lightest weight full featured twin chamber fork on the market. 

SPECIFICATIONS:

• Closed cartridge using a 25mm cartridge tube.
• Speed sensitive characteristics similar to the Lucky Carbon.
• Internal Huck Valve speed sensitive bottoming control.
• Can be setup for all riding styles, SX, MX, GNCC, Desert, and racing in high speed or aggressive conditions. 
• Sealed 25mm cartridge with 39mm spring charged ICS piston (2.0, 2.2, 2.5 kg/mm rates available). Closed cartridge design uses an IC spring and piston to 
  maintain cartridge pressure.
• Sealed cartridge keeps internal valving separated from outer chamber oil. This allows valving to stay clean and free of contaminants, which maintains 
  consistent operation over longer periods of use. 
• Closed cartridge utilizes a shim-tuned spring perch that creates a secondary viscous damping. Spring perch secondary damping is speed and position 
  sensitive and only available on the Blackjack systems.
• Compound leaf spring mid-valve design with 3 bending surfaces.
• Internal spring preload adjustment uses circlip design, making it quick and easy.
• Unique circlip retained compression adjuster assembly allows position of compression adjuster after fork has been installed. 
• Specific tools and advanced suspension knowledge required to service and maintain, available from MX-Tech Suspension.
• Available for WP (AER fork only currently), KYB, and SHOWA forks.
• External compression and rebound adjusters.
• Ultra low weight, low friction design.
• Lightest closed cartridge system on 
• Ti bolt package (axle pinch bolts, fork guard bolts)
