My son has an 05 KX 125 with the Athena 144cc big bore kit. He is wanting to go with some buddies to the dunes in western Oklahoma. I have never ridden a motorcycle on dunes, but it looks like fun. Do you guys think his bike will pull a paddle tire, or should I send him with one of mine? What kind of paddle tire is the best, and how much would one run? Thank you!
