My new Yager 200 "shudders" a bit when you start off from a stop. When I twist the throttle, the bike revs to around 3k rpm as it begins to move... and at this point it shakes or "shudders" a bit as it takes off. :-\ It doesn't do it around 3k rpm if you are already moving. I assume it's normal, and it isn't that bad, it's just kinda strange. I seem to remember my Vino 125 behaving similarly, but I'm a bit spoiled by how smooth my other bike, a Yamaha Morphous, is.

Have your dealer check the belt. This is behavior that generally happens on a worn drive belt, but it could just need some dicking around with (to use a scientific phrase). ;) It's under warranty, so no worries.

My Agility and now the Yager have this "judder" but mostly when I really crank the throttle, either from a dead stop or pulling a hill. I was concerned with the Agility 50 'cause it was always seemingly pulling a hill. The main point, it never changed. I think the Yager is the same. Chinese Scooters had a video of the CVT in motion and the belt goes several modes that seem impossible. I think that is the source of the juddering noise.
