Good security for your situation would be a heavy duty chain to an anchor point. For a new 250 Ninja, the railing is probably good enough to chain to. For a new 600cc supersport or new Harley more likely stolen, I would spend the money for a stronger anchor point set in concrete under the bike and a LoJack system. A bike cover also helps- stupid people often think it is OK to touch and sit on an uncovered bike, without asking first.
