RFX Pro Series Elite Aluminum Sprocket - 415 (Manufacturer Ref: FXRS 57-45 99BU)
Designed for demanding motocross riders, this RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum to provide an excellent balance between lightweight and durability. Its CAD profile and tight tolerances ensure precise engagement with the 415 chain, while the mud evacuation grooves minimize debris buildup on the teeth during muddy outings.
The sprocket is anodized blue, RFX color code for easy brand identification, and the RFX logo is laser-engraved for a polished finish. With its 45 teeth, it fits standard ratios for small displacement bikes and maintains a rigid design to withstand off-road demands.
Compatible with KTM 50 SX (2025), HUSQVARNA TC 50 (2025), and GAS GAS MC 50 (2025). Ideal for mini motocross riders looking for a lightweight, durable sprocket ready to tackle demanding terrains.
