SUNSTAR REAR SPROCKET ALUMINUM 51T-520 BLUE HUS/HUSQ/KTM

Engineered from premium aerospace-grade 7075-T6 aluminum, this 51T rear sprocket delivers exceptional strength without excess weight. Strategic perforation reduces mass while maintaining structural integrity. The proprietary tooth-and-valley geometry expands chain contact by 24%, optimizing power delivery and dispersing impact forces across a wider surface area for extended durability. Hard anodized finishing provides superior corrosion resistance and wear protection, making this sprocket ideal for demanding riding conditions on Husqvarna, KTM, and compatible 520-chain systems.
