Actually, that's exactly what I want to do with the bars! I just don't have the know-how to go about doing it myself.
The susspension is satisfactory for rough trails, but I don't think the tires are ever going to leave the ground.
I found a video of a guy stunting on his CBR125. He replaced the front cluster, the front fairings/headllight, and changed to mx bars. (You would need to, because the stock fairings would get in the way anyway)

That's what I would want to do. I'd probably put some white hand guards on it too. :)
