re: What ATV accessories should I get?

420 rancher is an awesome bike. You can fit 27 inch tires on it without lifting, but they are more nimble at 26. I own one and it is quality. Synthetic is safer to deal with(snapping or cutting your hands) than cable. It's lighter and stronger too. First thing you NEED, is stick stoppers and a ball. Don't leave the lot without them. Next would be rims/tires, then a 1500-2000 lb SEALED winch. Followed by nice front and rear extended racks. Also la guard dog or kolpin makes awesome strapless tie down systems for 125-150. Saves time and gas. They make swivel
Mounts for anything from beer holders to pistol holders, gps, etc, but those are not necessary.
Oh and spend the extra 3-5 hundo on power steering and thank me later.
