This is the first true innovation of the off-road air fork that helps manage the hyper-progressive nature of all production air forks. The MXT TAC-R system has been in development for an extensive period of time. The stock Showa TAC system required MXT to log countless hours in all riding applications as a way to truly deliver works level performance.
All air fork systems currently work by using single volume pressure regions. Air pressure changes depend upon the position of the stroke to change volume. This is similar to a hyper progressive spring rate, where the air spring is the largest contributor to net force, and the most changed as a function of position.
MXT saw a need to create a more linear force instead of the stock progressive characteristic. We created this by incorporating an additional compression region. The new high pressure region is positioned above the main pressure region and is separated by a piston. As the main pressure region increases, it reaches a point at which the separation piston starts to compress. This effectively slows the rate at which the volume change accelerates. MXT engineered this to occur in the middle of the stroke which limits the progressive nature of the air fork. Finally, near the end of the stroke, the compensation effect of the high pressure region stops. At this point the pressure dramatically rises to the benefit of maintaining the original air spring effect which allows for excellent bottoming control.
