yeah exactly how would you know it was taken on a trailer unless you watched it get taken or some other dumb ass sat there and watched it but either way that sucks and hope he gets it back in one piece and hence the reason i dont leave my bike anywhere i can not see it like malls,movies,ect.... it stays in my garage which has a alarm on the door as well does my house. Try tp post a pic or vin so we have something to go from. Good luck
