Description
A worn or stock countershaft sprocket directly impacts your FZ6R’s acceleration response and chain wear patterns. The Sunstar 16-tooth front sprocket restores precise gear engagement and extends drivetrain component life through superior material science and manufacturing tolerances developed over decades of Japanese OEM applications.
This bolt-on replacement pairs case-hardened chromoly steel with Parkerizing surface treatment to deliver the durability expected in high-stress drivetrain environments, while integrated weight-reduction drilling improves rotational efficiency without sacrificing strength.
