No, this sprocket is specifically designed for 520 pitch chains.
The sprocket itself is the main unit; please reuse your existing OEM retaining plate and bolts.
It fits various Yamaha YZ250, YZ250X, YZ450F, WR series, and Kawasaki KX250 models from 1999 to 2023.
It is highly recommended to replace both the chain and sprockets simultaneously to ensure even wear and longevity of the drivetrain.
It is constructed from high-grade steel for maximum durability.
Ensure the shaft is clear of debris or old grease build-up and verify that the splines are properly aligned.
Check that the chain is correctly tensioned and that the chain pitch matches the sprocket specification.
Installation should be performed while the bike is on a stable stand. Ensure the bike is in neutral before removing the front sprocket cover. Always verify that your chain is a 520 pitch before installing this sprocket; mixing pitch sizes will cause immediate failure. To maintain the life of your sprocket, keep your chain clean, properly tensioned, and lubricated according to your bike manufacturer's service manual. Periodically check the teeth for 'hooking' or wear; if the teeth begin to show a shark-fin shape, it is time to replace both the sprocket and the chain to ensure safety and performance.
