Interesting, I have got to the point where for security reasons I need to protect my pride and joy even before she is finished. Ground anchor is on hold as I am moving house but chaining to the bike lift seems a good option. Although as mentioned earlier a professional will defeat most security attempts you just have to make it too awkward to make it worth while. Read an article from a security chain manufacturer who has a "Page of Shame" where most of the current motorcycle security chains are tested including the Ride reccomended and Sold Secure items which fell to the charms of 42" Irwin bolt cutters which is the stock in trade tool for naughty boys. Also many chains will never resist an abrasive disc cutter even some of the low powered battery units. There was discussion about through hardened links or case hardedned, through hardened being more susceptible to cracking especially when treated to a spray of freezing agent.
It appears to stay out of the clutches of manual bolt cutters (Portable hydraulics are another problem) you need to go up to 19mm section links which in turn are heavy. Dont forget the crafty dodge that matey uses where you leave your chain chained to a fixed object and return each day. If the chain is sleeved they pull back the sleeve, cut the chain and make good with a cable tie, pulling the shroud back over to cover their evil work. You turn up next day and chain your bike up as normal never suspecting that it is only held together with a cable tie, the rest is.......
