I have had my Qlink XF200 for 3 weeks now. I am following the recommended break in procedure very closely. Qlink recommends keeping the revs low but not consistently low and not to max out the speed for 500 miles.
I now have 441 miles on it and today got it up to 70 mph. A little early but it was only for a short while. It is bone stock with no modifications. I was pleased that the Qlink's 200cc engine was able to attain that speed as my goal is to make this motorcycle cruise at 65 mph comfortably for a 38 mile round trip commute. So far the XF200 runs like a top.
