I am not bias one way or the other. I own both a 2 and 4 stroke. Both of which have their pro's and con's. I love my raptor on the woods, But get me on the dunes and i am dying to ride the shee. The 4 storkes are more user friendly, so when i take one of my less expeirenced friends with me they usually get to ride the raptor. Then as someone else had said, they complain about the shee when riding it because they cant keep it in the powerband, and are then amazed when i ride the piss out of it and blow by them
