If the claim is on USFS ground, and the Forest has implemented their Travel Management Plan, Motorized use is only allowed on desiginated roads and trails, no "cross country" use allowed. Most Forests will have a policy of allowing use within 100 to 300 feet of either side of the road for camping, etc., but check with the local District for details, and most of the time it is only for traditional campsites, etc.

 Check with the local Ranger District office for a free copy of the Motor Vehicle Use Map.

If on BLM ground, they have a different policy, being 'Open", "Limited" or "Closed".  If "Open", you can travel cross country as long as you don't damage resources.  If it is "Limited", motorized use is allowed on designated roads and trails, and other designated areas.  If "Closed", then motorized use is not allowed.  Check with your local District Office for status.
