First, complete the running. I don't believe in running but i won't recommend you to skip it. So, ride between 40-50kmph in first 200kms, 50-70 in next 200kms, do the first oil change when it is 400kms on the odo. This running is enough. Now ride it at different speeds as you like. When it is 1000kms on the odo take it to a good mechanic, get it tuned and the second oil changed. (I use ZIC HiFlo 20W-50, i would recommend ZIC HiFlo 20W-50 to you as well)
Now ride it like you have never ridden before. Euro2 CG125 engine is faster than all the previous models (never had a run with the pointer though). After 1000-1500kms it will easily do 110+km/h.
