RFX Pro Series Elite Aluminium - 428 SprocketRef : RFX00429A / 1123237014

The RFX Pro Series Elite crown made of 7075 aluminum is designed for motocross riders seeking a lightweight, durable part suitable for muddy conditions. CNC machined and crafted according to CAD profiling, it combines controlled weight reduction and increased rigidity to withstand the challenges of the terrain. The mud drainage grooves limit the clogging of the teeth, extending the lifespan of both the chain and the crown.

• Chain pitch: 428
• Finish: Blue anodization (color code according to brand)

As a standard replacement part, this crown is intended for motocross and dirt machines, particularly for smaller displacement bikes where the 428 pitch is common. It is compatible with several 85 cc models (e.g., KTM 85 SX, Husqvarna TC 85, Gas Gas MC 85) and is also available in silver to match different equipment and manufacturer color codes.
