Don't shoot me if this has been dealt with as I had a look with search, but couldn't find what I was looking for. Went to freedom motorcycles in brooky today and had a look at 2 disc locks. One for 60 one for 99, the more expensive one being stainless steel, ie not cuttable. I only have a little zzr250 but I want some peace of mind so I want something that will go off if someone sits on the bike. But tried these disc locks and they only go off if the bike wheel moves. First off is $99 a good price? Also, does anyone know of disc locks that are sensitive enough to respond to someone sitting on the bike? The lady assured me there was no such disclock alarm, but she's trying to sell me this one so not convinced. Regarding standalone alarms she said they're a waste as they just kill the battery and require constant battery replacing because of it. Feel free to say anything else useful about disclock alarms that I haven't thought of. Thanks.
