What's up with the stock front sprocket on the 05WR450

Had the same thing on my 2001 WR426.

Don't worry about it. I just changed mine out and threw the old one away.

No worries, I'm just curious what good it does?

Bump.....Any ideas

It's just there to reduce chain noise. You don't need it. (And I don't think it really does much anyways)

It is there for noise and vibration control. My XR650L has one on it also. It is not needed.
