I used to have 6 quads (family of 6) .. and we had a 200cc 2-Stroke Blaster for a short while.. literally only put maybe 5 tanks of gas through it, before I sold it..., cause I could never get the kids to ride it. It's like 3/4 size quad (compared to a 450 lets say).. The thing with it is I could keep up with 450s, but you have to keep that one in the power band at all times. I'd shift several times just in one dune. I think it's a 6 speed, with a tight gear ratio or something.
It has plenty of mustard if it's in the power band, but if your kid isn't proficient at shifting, it could be a challenge.
