I currently have a 07 summit X 800 159 and am thinking about a different sled. I am looking for opinions from people who have rode both the apex and rev. I know the apex will be heavier, but with a few mods can it be made to handle and climb like my summit? I am not interested in putting a turbo on it. Just looking for a 150hp machine that that will do what my summit will. Can I make an apex work or do I have to go XP?
