What size of rear sand stars should I get on my stock 400ex? I already know I'm getting .160 size wheels.

 

Again the 20x11x8 beacause of the power delivery of the 400. If you make it a 440, the tire would have to be bigger.

 

Anybody else?

 

I'd stick with the 20" tires, not because of power delivery, but due to gearing changes, clearance issues, etc. Since the ex is a fairly light bike, you don't need a bigger tire like the DS or the V-Force. You'll be happy with the Sand Star.

 

Anyone else?

 

I've decided to get the sandstar on .125 rim size 20-11-9.

 

That's what I have, but may I sufggest going down 1 tooth on the counter sprocket as I have done and found it works real well in the sand.

 

what's the counter sprocket? The front sprocket?
