Manufacturer reference: FXRS 61-50 99RD

The RFX Pro Series Elite sprocket made from 7075 aluminum is designed for demanding motocross riders looking for a lightweight and durable part for their 520 transmission. CNC machined and anodized in red, it combines a racing aesthetic with a refined finish: laser-engraved RFX logo and color coding suitable for models for a coordinated look with the machine.

• Material: 7075 aluminum, CNC machining for manufacturing precision.
• Number of teeth: 50 — chain pitch: 520 (compatible with 520 transmission).
• Mud drainage grooves to limit dirt accumulation between the links.
• Optimized CAD profile to reduce weight without compromising rigidity.
• Tight tolerances for more consistent chain/sprocket contact and more uniform wear.
• Anodized finish (red): corrosion resistance and racing look.

Designed for off-road use, this sprocket fits many enduro and motocross bikes, including the BETA RR 430 and RR 390 (2023 models) listed among the common applications. Ideal for those looking to reduce unsprung weight while maintaining a robust tooth profile and reliable performance in muddy terrain.
