mine was the only sport bike there. there was a HD on a lift, one in the front show room and some yamaha cruiser next to mine....NOT A INSIDE JOB hahaha...Sounds like a big fat yes to that. Your bike was in a shop with 4 other bikes and they took yours. How did they get in there in the first place. Who tipped them off to this shop? Who tipped them off to this bike? Most likely someone you know or someone that has seen this bike before or someone that works there. Its very cut and dry now go gather evidence and prove it...GOOD LUCK FINDING IT...
