I think that you will find, and I think some of the posts on this thread confirm, that many mc riders assume that once you get a small bike you will want a bigger/more powerful bike.
That has not been my experience. I bought as my first bike — to be carried behind our ExPo vehicle — a Yami WR250R on the basis of several recommendations from some experienced ExPoForum members. I did not like or ride the bike well, and after crashing it hard I sold it.
In replacement, I bought a Yami TW200, and I am delighted. I can ride it on pavement, but more important I can ride it very confidently on dirt and gravel, all the places I might have to use to get out of where our larger vehicle might get stuck, and certainly where I want to explore after we park the bigger vehicle.
So, I'd say: assess YOUR needs and buy accordingly. Don't be too much swayed by others who may have different needs/appetites.
