The 02' Raptor isn't worth 4000$. I HATE honda's so i don't know what yours is worth.
The Rancher is useless as a utility, due to no 4x4, fun wise. As a trail and yard work i'm sure it's perfect. My buddies 420 is 4x4 and I'll take my old Polais 250, or my other buddies grizzly 350 over the honda ANY DAY.
The Rapdaddy, has dual carbs, and has reverse. It's a switch on the right front fender. It's a wonderful and fun bike. Put some gears on it and bigger more aggressive tires and you can tear up the mud too.
What do you have in the Honda?
