guyz the ds 90 is probobly the best youth quad ever. i am 13, my cuz that is 8 came ova for my birthday. We went to my friends house and his little bro got the 90. My cuzin has a rptor 80 or 90 i forgot. he said that the 90 is was better, (he took the govener out of the ds)
it has enough power, (for kids) i even thought it was great for tykes. The handling i think could improve a little
