The Dirt Tricks KX-50-Z-C Rear Sprocket is engineered for durability and performance, designed specifically for Kawasaki motorcycles with a 520 chain. Constructed from high-quality chromoly steel and coated with advanced zirconium, this sprocket offers a perfect combination of strength and lightweight design. Its innovative “minimalist” appearance provides a sleek look while maintaining maximum durability for rigorous off-road riding. The zirconium coating reduces friction by up to 50%, which enhances efficiency and extends sprocket life, making it an excellent choice for riders seeking long-lasting performance. Developed by Dirt Tricks president and engineer Greg Burns in 2002, this sprocket incorporates aerospace-grade steels, heat treatments, and FEA stress analysis to ensure it withstands the demands of a full season of aggressive riding. The design surpasses stainless steel in strength by approximately 2.5 times, providing exceptional resilience against wear and impact. Its lightweight construction rivals aluminum, offering a significant reduction in weight without sacrificing strength, which can improve overall bike handling and acceleration. Available in the distinctive Diamond Black and Chromatic finishes, the Dirt Tricks Zirconium Rear Sprockets are visually striking and built for performance. Each sprocket is backed by a one-year guarantee—if it wears out during normal use, Dirt Tricks will replace it.
