Here in WA State we have the good to go, the first gen motorcycle transponder was more like a thin brick than anything, I had mine mounted just behind the rear seat and mounted securely to the rack. Worked quite well. We have since gone to a very small stcker that mounts to the headlight, mostly transparent, with the exception of the small RFID tag. I know use the brick on the klr mounted on the front of the fairing, KLrs aint 'sposed to look purty, so who cares? It works!!!!!
