I have the Triumph alarm which is a Datatool one fitted and it also auto sets after about 45 seconds. The Triumph keys are coded to the ECU so effectively immobilise the bike if the correct key is not used. I also use a Triumph Artego U lock on the front and an ABUS Granite disk lock for the back. The U-lock can also be used to attach bike to appropriate street furniture, if available, instead of going through the front wheel. Councils really need to put decent street furniture in more places to attach bikes to. I realise that none of the above will stop a determined thief but hopefully it is enough to make most of them go elsewhere.
