Ok I have a ATC250SX. I made a 7 inch longer swing arm. I know its shaft drive but i had to make the shaft longer to.Check out my pics. Anyways Imgoing to the dunes and need tires. Do ya think the 250SX has enough power for paddles.

 

I have a ATC250sx and i think it definetly has enough power for paddles. People would be surprised by how much power it actually has. I use to use mine all the time for mudding, but my swingarm bearings took a poop. I cant help you with what size paddles to use but if you know the part number or can point me in the right direction with what bearings i need pm me.

BTW, your rear tires look exactly like my rears, are they made by Carlisle (sp?)?

 

The tires are trail masters or something.
