ART Dual-components aluminum/steel Ultra-Light mud-resistant sprocket 808 - 520 (manufacturer reference: ART-808-49-BLK): a bi-material sprocket designed for offroad and road practices. It combines an ultra-light inner part made of 7075 T65A aluminum with a hardened steel outer sprocket, offering a balance between lightness and durability. Designed to shed mud and limit dirt adhesion, it facilitates chain rotation in demanding conditions.

Tested for endurance and approved by European teams, this sprocket is aimed at motocross riders and roadsters looking for a robust part capable of withstanding intensive sessions. Its construction reduces unsprung mass compared to a full steel sprocket while maintaining a steel wear area for resistance against chain contact.
Compatible with many 520 motorcycles, notable references include: SUZUKI RM-Z 450 (2022), SUZUKI RMX 450 (2019), and SUZUKI RM-Z 250 (2018). Standard mounting: check the pitch and number of teeth of the sprocket for optimal fitting.
