JT Sprockets Ultra-Light Aluminum Sprocket 478 - 520 (Manufacturer Part No: JTA478.43BLK)
Designed for riders seeking a lightweight and reliable transmission, this JT Sprockets sprocket utilizes aerospace-grade 7075‑T6 aluminum (Ergal) for an excellent balance between strength and weight reduction. Its "mud-resistant" finish minimizes dirt accumulation and facilitates debris removal, making it useful for road riding and changing conditions.
This transmission part is intended for replacement or gearing changes, and is machined to withstand common stresses while reducing unsprung inertia. The machining and finish make rear wheel maintenance easier and limit mud accumulation between teeth and flanges. Particularly suitable for roadsters and sport-road bikes in the 520 chain configuration.
Common compatibilities: KAWASAKI NINJA ZX‑6R (2025 - 636 cc), KAWASAKI NINJA ZX‑6 R ABS (ZX636G) (2021 - 636 cc) and KAWASAKI NINJA ZX‑6 R ABS KRT EDITION (2020 - 636 cc). Check the number of teeth and chain pitch of your motorcycle before installation.
