RFX Pro Series Elite Aluminum Sprocket - 428 by RFX: a sprocket designed for enduro and motocross, combining lightweight construction and precision machining. CNC machined from 7075 aluminum, it features a CAD-designed profile that reduces mass without compromising rigidity. The mud evacuation grooves facilitate self-cleaning of the drivetrain in muddy conditions and contribute to a cleaner interaction with the chain.

- Usage: Standard type, suitable for motocross/off-road use.
Anodized finish available in color coded according to motorcycle brand — here in blue — to harmonize the look of the machine. Designed to withstand lateral forces thanks to a rigid geometry, this sprocket is an aesthetic and functional choice for those looking to replace or upgrade their chain/sprocket setup on 85cc machines and other compatible models.
