my 19 mo old son already knows what the gas is for he found out the hard way my fault though.left him on my 800 so i could open gate to pasture,next thing i know he cracked the throttle and went tumblin off the back good thing he landed in soft snow.lesson learned dont leave your child on sled while running.never saw a little boy love riddin so much as him,my eleven yr old daughter loves it too.my wife also,it is great fun tme with the family.
