RFX Pro Series Elite Aluminum Sprocket - 420 (Manufacturer Part No: FXRS 37-45 99BU)
Designed for dirt and muddy conditions, this RFX Pro Series Elite sprocket combines lightweight and durability. CNC machined from 7075 aluminum, it features 45 teeth with a 420 pitch, a CAD-designed profile, and a blue anodized finish that matches the colors of motocross machines. The mud evacuation grooves limit dirt accumulation between the links and the sprocket, contributing to more controlled wear of the transmission.
Ideal for motocross enthusiasts looking to replace their sprocket with a lightweight and refined part, it is specifically compatible with YAMAHA YZ 65 models (2024–2026). Check compatibility with your pinion and chain pitch before installation.
