RFX Pro 14 Teeth Output sprocketRef : RFX00543A / 1123260002

The RFX Pro front sprocket with 14 teeth is designed for motocross and enduro riders seeking a robust, lightweight, and mud-resistant sprocket. CNC machined from high-strength steel and treated with carburizing for high hardness (≈60 HRC), it withstands the wear of the terrain while maintaining a precise profile for clean chain engagement.

• Number of teeth: 14
• Chain pitch: 520
• Material: High-strength steel
• Finish: Black zinc to limit light corrosion
• Design: Lightweight holes and anti-mud grooves on both sides
• Version: Anti-mud (optimized dirt evacuation)

The lightweight drilling reduces rotating mass without sacrificing strength, while the self-cleaning grooves limit mud accumulation to preserve the sprocket/chain interface in muddy conditions. Its black zinc finish provides protection against wash water and a sleek look on the bike.

Main compatibility: suitable for 520 drive chains on motocross/enduro models — including HONDA CRF 250 RX ENDURO (2021/2020) and HONDA CRF 250 R (2021). Manufacturer reference: FXFS 17-14 99BK.
