RFX Pro 14 Teeth Gearbox output pinionRef : RFX01189A / 1123253002

RFX Pro Sprocket 14 Teeth: a front sprocket designed for aggressive trajectories and daily maintenance. CNC machined from high-strength steel and then carburized (hardness 60 HRC), it offers a solid structure capable of withstanding sustained demands on trails, tracks, or roads. Designed for a 520 pitch chain, it fits the transmissions of quads, motocross bikes, and demanding roadsters.

• CNC machining for precise tooth geometry and smooth engagement.
• Carburizing at 60 Rockwell degrees for better wear resistance.
• Lightening holes to reduce rotating mass without compromising strength.
• Mud evacuation grooves on both sides to limit accumulation and facilitate cleaning.
• Black zinc finish: lightweight anti-corrosion protection and a neat look.

This RFX Pro sprocket focuses on durability and practicality: less mud buildup, consistent drive behavior, and a finish that withstands washing and the elements. Ideal for riders who frequently change gears or restore their transmission without sacrificing aesthetics. Manufacturer reference: FXFS 11-14 99BK. Suitable for Quad, Cross, and Roadster universes (compatible with 520 chain).
