Like disc locks, chains’ effectiveness, though better than nothing, are only really any good if the bike is chained to something solid. If it isn’t, the bike is simply locked or chained to itself, which does not prevent the bike being very simply lifted and dumped in a van.
As with most threads of this type (which are not particular to a water cooled GS) it dissolves down into one bod saying, “I use XYZ and my bike hasn’t been stolen”, followed by another saying “I use ABC and mine hasn’t been nicked”, followed by “But I use 123 with the addition of 7 * and it hasn’t been stolen”, culminating in the all but inevitable “I don’t use anything and it’s not been stolen”, all of which only boils down to the simple fact that all four of them had a pound of butter in the fridge.
Use whatever method suits you best, whilst remembering that bods on this site report:
A. I only left my bike for two minutes, whilst I bought a coffee. This of course ignores that nothing really only takes two minutes and that he couldn’t be arsed to lock it.
B. Thefts from outside their house of bikes that are chained and alarmed to the hilt.
Of the two, scenario A is probably the easiest to potentially avoid, by taking the real 30 seconds that it takes to put a dic lock on, extending your ‘two minute’ coffee break by half a minute only. Scenario B only shows that if someone wants it badly enough and they think / know that they can probably get away with pinching it, they will (maybe) at least attempt it. As to those that leave their £15,000 plus motorcycle, parked all day with nothing but fresh air to protect it….. good luck.
