JT Sprockets Racelite Aluminium Rear Motocross Sprocket – 50-Tooth (50T) | Satin Black Finish

Unleash the ultimate in lightweight racing performance for your machine. The JT Sprockets Racelite Aluminium Rear Chainwheel is precision CNC machined from certified 7075-T6 Ergal aviation-grade aluminium alloy. Fully heat-treated for maximum wear resistance and surface hardness, this elite sprocket range is engineered to withstand extreme pro-race conditions, providing maximum structural strength at the absolute minimum unsprung weight.
Manufactured by the world’s leading sprocket brand to strict Japanese OEM standards, this sprocket features a specialized self-cleaning mud groove design. This ensures track dirt, grit, and sand are swept away from the chain rollers, reducing drivetrain friction and preventing power loss when you're on the gas.
