No, it is specifically designed for Yamaha YZ125, YZ250, and WR125 models manufactured up to 1998.
It is CNC machined from 7075 aerospace-grade aluminum.
No, it is designed to use your motorcycle's existing OEM mounting hardware.
Use a soft brush and mild degreaser during your routine bike wash to clear out any packed mud or debris.
While 7075 aluminum is incredibly strong and lightweight, it will naturally wear faster than hardened steel, making it ideal for racing applications where weight saving is a priority.
Check the chain alignment and tension. Ensure the chain is not worn, as a new sprocket paired with an old, stretched chain will cause noise and accelerated wear.
Verify that your chain is properly lubricated and that the chain tension is not too tight, which can cause excessive friction on aluminum.
Installation of the Apico Evolite Rear Sprocket is straightforward as it is designed to match OEM specifications for Yamaha YZ125, YZ250, and WR125 models produced up to 1998. To install, remove the rear wheel, unbolt the old sprocket, and attach the Evolite unit using your original hardware. Ensure the sprocket bolts are torqued to the manufacturer's recommended settings. For long-term care, regularly inspect the teeth for hooking or wear, clean the dirt groove during your post-ride wash, and always check that your chain slack is within the manual's specifications to prevent undue stress on the aluminum teeth.
