RFX Pro Series Elite Aluminum Sprocket - 420 (Manufacturer part number: FXRS 26-48 99GN) — A sprocket designed for motocross riders seeking lightweight and durability for their machine's final drive.
- Material: CNC machined from 7075 aluminum for a good weight/durability compromise.
- Number of teeth: 48 teeth — CAD optimized profile for precise tooth design.
- Chain pitch: 420, compatible with small displacement motocross transmissions.
- Finish: green anodization, laser-etched RFX logo.
- Design: mud evacuation grooves to limit accumulation and extend the lifespan of the chain and sprocket.
- Precision: tight tolerances and increased stiffness for better torsional resistance in off-road use.
Designed for the terrain, this RFX Pro Series Elite sprocket minimizes unsprung weight while remaining suited to the rigors of the track. Its color coding makes it easy to identify in the workshop and allows for matching the transmission to the machine's aesthetics. Intended for motocross bikes and compatible with several KAWASAKI KX 65 models (2021, 2025, 2026), it is suitable for standard builds and original replacements based on 420.
