I know but 2 discs locks and a feck off big chain will take longer and hopefully are a slightly less attractive prospect than the posh expensive bikes I try to park next to with just one form of security.
(i ride a '98 BMW r1100rt so its hardly an attractive bike for thieves in the first place)
Have you not seen any of the vids of cunts taking 10 minutes grinding away. Plenty of people watching them but they just scare them off by threatening them with the grinder and/or a big hammer
There's no point. They just grind the disc away.
