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.
The SKF TAC Glide Kit
The InnTeck Glide Kit replaces the stock cartridge rod seals and air divider piston seals in the new Showa SFF-Air TAC fork would they be the Honda or Kawasaki/Suzuki variants.
The Showa SFF-Air TAC fork features many internal seals and 3 of the 6 seals are subject to very high pressures, therefore generating much more seal drag (friction)and stick-slip when compared to conventional forks.
InnTeck utilized world class bearing and seal manufacturer SKF’s expertise in creating replacement seals that feature less seal drag (friction),less stick-slip and better sealing. This was accomplished by using an SKF special compound with tailored seal design. Combining SKF technology with dedicated machined components, allows InnTeck to accomplish better sealing capabilities, less drag and reduced stick-slip while being able to use 1 cartridge seal in place of 3 or 2. Therefore, eliminating two points of seal drag!
The updated forks benefit from less seal drag (friction) and virtually eliminated stick-slip. The rider will immediately feel better small bump absorption during braking, less arm pump and smoother feel. The reduced friction also allows for better damping, making the forks more responsive to clicker settings.
