Had to take my buddy's son to school this morning as his transporter click was stolen. This makes about four bikes of people I know stolen in the last year and I am wondering how they are doing it. Are they using master keys, or do they have some sort of device that they jam into the ignition key switch? Most of these thefts were in crowded areas so a pick-up hoist was unlikely. Any body know the MO these guys are using? At any rate, a tough lock on the disk is a good idea, and I am thinking also about putting in a hidden switch that connects the live 12 VDC to the horn. That way, unless I turn the secret switch off, the horn blows as soon as the ignition comes alive.
