RFX Pro Series Elite Aluminum Sprocket - 420 (Manufacturer part number: FXRS 56-48 99RD) — a component designed for motocross, machined from high-strength 7075 aluminum and anodized red for a racing look that stands out on the bike as well as on the podiums.
Engineered for demanding riders, this 48-tooth sprocket with a 420 pitch combines lightweight and durability: CNC machining, CAD-defined profile, and mud evacuation grooves to minimize accumulation and wear on the chain. The RFX logo is laser-engraved, and the anodized finish ensures color retention during muddy sessions.
Ideal for motocross and compatible with many small single-cylinder bikes (e.g., KTM 65/60 SX), this sprocket is aimed at riders who want a lightweight, precise, and easy-to-maintain component after a day on challenging terrain.
