JT Sprockets JTA808.51BLK Sprocket — designed for motocross riders who want a lightweight, durable, and easy-to-maintain transmission. This "ultra-light" 7075-T6 aluminum (Ergal) sprocket combines rigidity and reduced mass to limit unsprung inertia during jumps and changes of pace on the track. Its mud-resistant finish helps to repel debris and keep the chain cleaner between races.
Ideal for replacement during gearing adjustments or to reduce peripheral weight without sacrificing strength. It easily installs in place of a standard 520 sprocket and is suitable for motocross setups where robustness meets lightness.
