Sirris F43 CMX Front Fork | 220 mm Travel | Arctic Leopard XE Pro S

The Sirris F43 CMX is a bolt-in upside-down fork upgrade for the Arctic Leopard XE Pro S and XE Pro S Enduro. Its closed-cartridge CMX (Compact Motocross) damping gives you tool-free compression adjustment and plusher, more controlled travel than the stock fork.

Fitment

• Fits the Arctic Leopard XE Pro S and XE Pro S Enduro.
• Does not fit the XE Pro R, which uses a different brake bracket. Choose the XE Pro R version instead.
• Early XE Pro S bikes may need a direct-mount stem because the steerer can't be clamped. Later bikes already have one.
• Includes a 220 mm rotor brake bracket and XE Pro S wheel spacers.
