TheTile? It only works up to about 30 feet.
Former owner of a 99 Valkyrie for 15 years.
Really hadn't planned on putting an alarm system on my new F6, because I too felt like it's too heavy for most thieves to move. However, my son-in-law, a BMW rider, just gave me a Gorilla Cycle Alarm System as a Christmas gift, so I'm going to have it installed once the weather permits getting it out of the garage for a ride. I may not use it much, but will definitely activate it when I'm away from home overnight. Unexpected, but a nice gift.
