Y 125ZR GP Edition is the official name for this bike by HLYM. I thinking that this name refers to a limited edition. The other 125ZR which is in the red and black are named officially Y 125ZR Black and Y 125ZR Red. If this is the limited edition, we might only see it for just few more month before it disappears from the shop. So, if you are thinking to get it, just go and get now!
