• 44-tooth rear sprocket for tuned acceleration and gearing response
• 100% designed and manufactured in the USA

Steel construction makes the 611ZK-44 ideal for street, track, and aggressive riding applications where longevity is a priority over weight savings. Hardened teeth maintain their profile over thousands of miles, ensuring consistent chain mesh and efficient power delivery throughout the sprocket's service life. This sprocket is a direct bolt-on replacement that installs with factory hardware.
