Stolen Bike in Montana

We got this note on a stolen bike in Montana:

My name is Jason Steffins and I am a 5-time Montana Vet-Pro State Motocross Champ and one of my bikes was stolen last week from my house in Helena, Montana.  It is a 2009 Kawasaki KX450F VIN# JKAKXGEC59A000576 Race#808.  Thank you very much.  I understand if you're unable to post it, but I'd greatly appreciate it. Take care.
