In a shed you can use a slightly longer or heavier duty chain than you would on the street, as you don't have to take it with you when you ride off. Wooden floors and walls make lousy anvils for smashing chains, but still try to ensure the chain doesn't rest on the floor. Park the bike in tight to the shed wall with the steering lock on. Try to pass the chain through the frame or swingarm as well as through the wheel (though it's better to secure just a wheel than not bother fitting the chain at all) with the lock accessible only by leaning over the seat. This will make it almost impossible for a thief to attack the chain. An additional disc lock on the front wheel may add further piece of mind. WE USE:Abus Granit Power Chain 37 RiDE-December 09
