i have the versa rack system on my foreman. it mounts with clamps that go around the factory rack and a bolt to tighten. it is very secure and mine has never moved or shifted. these racks are all steel and you can lift the atv with them. down side is that they are a bit heavy. for trail riding especially overnight stuff, you can really load them up and weight doesn't matter too much. when i'm not loaded heavy, i unbolt the rear section to save weight and bolt aluminum flat stock in it's place. it is strong enough that i adapted a spare tire rack for the real long haul stuff.
