Idle speed

1450 rpm +/- 100 ish. You shouldn't adjust it though. If you play with the cable to make it go quicker you will increase idle, but you will burn out some other electrical component. I remember this was an issue on the 125's. They are electronically controlled. If you are having issues with it, take it back to the dealer or risk doing it yourself and pooching your injection system. As per the 125 service manual, it warns against adjusting the white painted screw (Idle). Failure to heed the warning may result in throttle valve and idle control damage.
