Suspension

The SX and XC come with a WP XACT fork and rear shock, while the W and EXC come with XPLOR suspension. In particular, the Factory Edition fork has calibrated pistons for tighter mating, which makes it possible to increase the pressure in the forks. The rear shock has a preload adjuster for more precise adjustment. The traverses resemble the Xtrig traverse structure, but the aluminum profile is much more rounded and more milled in the center sections.
