JT SPROCKETS Ultra-Light 486 - 520 (Manufacturer Part No: JTA486.48BLK)
Designed for roadsters and compact machines, this JT Sprockets crown showcases the brand's expertise in final drive systems. Machined from 7075-T6 aerospace aluminum (Ergal), it features an ultra-light design intended for standard replacement or gearing changes.
The meticulous black finish and optimized tooth profile ensure a clean fit and aesthetic integration on most drivetrains. Lighter than a steel crown, it helps reduce unsprung mass and the load on the chassis without compromising chain reliability when maintenance is properly observed (appropriate tension and lubrication).
Common compatibilities: KAWASAKI NINJA 250 R (EX250K) 2011–2012 and other roadsters using a 520 pitch and a 48-tooth crown. Ideal for direct replacement or adjusting the gearing according to your riding style.
