It does great. It's the perfect size for a kid his age. He can handle it in difficult situations and it's fun watching him and his other little buddies getting unstuck on the rare occasion that it happens. We make them work it out when they can.
I cut a 144" Camo down to 1 1/2" to clear as well as making it managable for the small motor. The 485 is pretty much stock with an Aaen pipe and the oil injection removed to clean things up under the hood. It's definately a head turner on the hill, especially when he out climbs much bigger sleds.
