Alright here's a pet peeve of mine. People responding to a post without reading the posts before it. Why ask a question if it's been answered a few lines above or in a previous post that you have been given to read?

Sorry had to get that out of my system. I feel better.

The answer is 1500 world wide. With only 1500 it is not uncommon not to see very many around your area. Like I said that's 1500 world wide. We know there is one in England, another in Egypt and some other non North American countries. In Canada there has to be at least 500, so doing simple math would mean that there would be less then 1000 in the USA. There is about 312 million Americans and out of that lets say 6 million bike riders.
So only .00016 people would own a Stryker. Give or take a decimal moving one way or the other. Just a little more food for thought. If you move the decimal to the left one more and add the 0, that's your chances of winning the Power Ball. 8)
So your chances right now of seeing another Stryker is just a little better then winning the lottery. We haven't had the amount of time HD has to saturate the market, so that the only bike you see is a HD. ;D
