Anyone on the fence about using a full size bike for their kid.... My son's 10 and dirt bikes a whole lot... That being said we set up a yz250 and a camso .... He was able to ride across asphalt and then ride all day with just the occasional help... Really no more than some full size adults I ride with[emoji23].. so really I would not waste your time just go full size... And a 2 stroke is way light for them... Video below.
