well youwant some good tires for mud and snow (i have razr2's the best of razr's) if its a lot of snow and if you're gunna go to the dunes then paddles would be good for both. trx 400ex is the perfect fit it seems like.

 

trxguy9780 so a 400ex will handle aperson on the back? I wont be riding in the snow that often cause quads arent allowed on the trails in the winter only sleds but i may occasionally do some riding down them. thanks
