Recently bought a Sportman 300 for the wife which means I don't need the rear seat on my 08 Sportsman Touring 500. Does anyone know of an aftermarket replacement (like a rack etc.) that would pop on where the seat is?

 

I know Artic Cat makes a rack to use when the second seat is removed from the TRV model they have............Not sure about Polaris though......Caper...........

 

I think this is a box that will fill in where the seat is and give you good storage. Pure Polaris : Lock & Ride? 1-Up Touring Rear Cargo Box)

 

Moose is right. I did see once on the trail someone had a custom rack made for one. Looked very nice.
