Having never owned a dirt bike or four wheel got both my sons ones a 110cc and 125cc and after some idiot moves on my part and rigging up on the 125 they are a ball to ride and my youngest going from the little battery powered to the 110cc within an hour had the thing flying. My oldest did not like it but I got on the 125cc and me weighing 245 that thing flew. Only thing I noticed was it bogged down on take off but once going it moved.

 

i'm close to the same size and when i test drive a 110cc after i fix one, it usually bogs a little just from the weight and the CVT/Belt trying to grab. kind of similar to a lawn tractor that is running and then you engage the blade. short duration of bogging.

 

if it's your carb, then it would bog in neutral also.

 

OK I hope I did not miss something again. I do not see a way to change gears when u accelerate the bike goes.
