This heavy duty adjustable camshaft sprocket is a must have upgrade for your Honda CRF110F, MSX/GROM125 & SF or Z125 Monkey, Not only is it adjustable to help give you that little bit more top or bottom end performance, it is heavy duty so even if you keep it at the stock timing, you can send it as hard as you like without worrying about the factory cam gear failing and causing catastrophic engine damage.
Gains in performance vary based on engine modifications.
※ This Adjustable Cam Timing sprocket is a Heavy Duty replacement for OEM 14321-KYY-900 and 14321-KYZ-900.
