put the atv's in a shed or garage? mine sits in my garage with the front door wide open..
 
get some barg anchor chain lol just lay it on top they wont get it off lol

Bahahaha! I'm laughing at the thought of someone lifting one of those chains. You might need to upgrade your suspension before laying one of those over your quad. And maybe a winch to pick up the chain. Hahaha

Do you have to keep your quad outside in the open? If so, try using a winch and pull the quad up in the air over a big ass tree branch. If it keeps bears from getting food, it should work from keeping theives from getting your quad.

I had to cut one of those Kryptonite locks at work and I thought I was going to pass out. I managed to get it, but that thing put up a fight!
