I'm in Utah, and my local dealer claims hes never seen a modern Kawasaki (since the mid 90's) come into his shop ...large bikes.... (new, obviously) that was not California spec. Based on that, I'd assume Utah, Wyoming, Nevada, oregon and such would see the same bikes, too. Probably more surrounding states, but I was never very good at remembering my states. I get mixed up with Washington as our United states has two or three Washingtons, I think...
ANyway, the cal bikes get sold to other places, so its nto surprising you'd see one.
