Hi mate

Try this and look under trackers keep flicking through untill the last slide,
They are more expensive than an alarm, but its way more likely ur gonna get it back,
i know if a local audi garag that kept having audi tt's stolen, bout 3 a month, so fitted trackers to all the r cars they get in, sure enough 3 audis missing, 3 ppl arrested, 3 cars returned!!
IF ever i get an expensive bike ill get one!!
