Features

RFX Pro Series Elite Aluminum Sprocket - 420 (Manufacturer Part No: FXRS 37-47 99BU)

Designed for off-road use, this RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum to strike the right balance between weight and strength. Its CAD-designed profile reduces weight without compromising rigidity, while the blue anodization provides a racing look and abrasion protection.

Material: CNC machined 7075 aluminum
Number of Teeth: 47 teeth (sprocket)
Chain Pitch: 420
Color: Anodized blue
Type: Standard, color code by model
Laser-etched RFX logo
Mud evacuation grooves to limit chain/sprocket clogging
Tight tolerances for precise chain engagement and better longevity

Intended for motocross riders seeking a lightweight and reliable part, this sprocket is particularly compatible with Yamaha YZ 65 (2024, 2025, 2026). Its machining and design promote controlled wear and consistent performance in muddy or dusty conditions.
