PBR Twin Color Ultra-Light Aluminum Sprocket 702 - 520 (Manufacturer Part No: 702 52 TC4)
Specifically designed for motocross, this PBR sprocket combines lightness and robustness. Precisely machined from 7075 T6 aluminum, it features a dual-color hard anodized finish (black/blue) that protects the surface and gives a racing look to your swingarm.
The geometry of the teeth and the weight-reducing cutouts make this sprocket a suitable choice for MX, SX, and enduro, where the terrain often loads the transmission. Compatible with 520 pitch transmissions, it fits many motocross models (e.g., SHERCO 450 SEF-R Factory 2022, BETA RR 390 4T 2020, GAS GAS EC 250 F 2015). For riders looking for a lightweight, durable part with a polished look, the 702 52 TC4 remains a serious and technical option.
