RFX Pro Series Trials Aluminum Sprocket - 520 (Ref. FXRS 91-41 99RD)

Specifically machined for off-road disciplines, this RFX Pro Series sprocket is crafted from 7075 aluminum using CNC machining for a well-balanced weight/stiffness compromise. Its red anodized finish and laser-engraved logo give it a racing look that matches modern trial and motocross machines.

• Material: CNC machined 7075 aluminum
• Number of teeth: 41 teeth (optimized CAD profile)
• Chain pitch: 520
• Mud drainage grooves to limit chain/sprocket clogging
• Color code according to brand and red anodized finish
• Stiff design for better torsional resistance and tight machining tolerances
• Type: standard

Designed for the demands of the terrain, this sprocket makes transmission maintenance easier by reducing mud accumulation and maintaining an accurate profile for proper chain guidance. Compatible with many 520 models, it fits particularly well with 300cc off-road and trial machines (e.g., Beta Evo 300, Sherco 300 ST, Gas Gas TXT 300). Installation and verification by a professional are recommended to ensure proper gearing and chain tension adjustment.
