Sirris F43 CMX Fork for Arctic Leopard XE Pro R [220mm Travel]

Upgrade the Arctic Leopard XE Pro R with the Sirris F43 CMX Fork, a purpose built high-performance suspension setup designed for aggressive eMoto riding.

The F43 uses Sirris’ CMX Tune, or Compact Motocross Tune, with a symmetrical adjustable closed-cartridge damping system, high-flow pistons, fully tunable compression and rebound valving, and separate lubrication and damping oil circuits. The result is consistent, predictable suspension performance through hard trail riding, jumps, repeated impacts, and long riding sessions.

With 220mm of travel, 43mm high-tensile steel stanchions, a hydraulic bump stop, and an ultra-stiff race-grade axle, the F43 is built to provide increased front-end support, steering precision, and bottom-out control when pushing the Arctic Leopard XE Pro R harder.

The fork also features 178mm spacing for a wide range of dirt and street tire options, replaceable brake caliper mounting brackets, Arctic Leopard-specific wheel spacers, and a billet aluminum drop clamp.

We highly recommend pairing this fork with the R38 Shock and TMB Linkage.
