I just bought a front sprocket -2 , and when I took off the original one - Boy was there a difference . The stock one is heavy and beefy. Does Kawasaki make a STOCK front sprocket -2 or -1 ?? I want a Heavy duty one..

Thanks...

If I had to guess I'd say you got an aluminum one - that's going to be your weight difference. Aluminum is fine, less rotational mass is a good thing for acceleration, but if you really want something beefy just shop for a steel sprocket. I'm sure I've seen them somewhere, if I can find them I'll post a link.

Nick,
No one in their right mind would even make an Alumunium front sprocket, What he got was just a steel sprocker without and spacers and or cushing added on. JMS, you'll be fine the sprocket will float on the spline within the clearance and help tp align the chain better.

Well crap, I read too quick. I glanced at the page and saw the aluminum rear sprocket but didn't actually look to see if the front was aluminum.

I guess aluminum can't handle the wear or the RPMs the smaller sprocket sees?

Well mostly the torque. Look around these forums a bit at Hot rod's posts. Somewhere on one of them you'll find an explanation of the kind of loads endured by the sprockets.
