Description
Fits: Arctic Leopard XE Pro R
The XE Pro R takes its own fork because of its brake bracket. For the XE Pro S or Enduro, see the XE Pro S / Enduro version.
The Sirris F43 pairs an oversized 43 mm chassis with the CMX (Compact Motocross) tuned closed-cartridge damper. Tool-free compression adjusters give nearly 30 clicks of quick external adjustment, and the direct-mount crown bolts to a 4-bolt direct-mount stem.
