Hey ya'll, I been cruzin around the forums tryin to get enough info to make a good decision. I have a daughter who is 9 years old, 4ft tall and 75lbs. She has been woods ridin for 2 years and raced in 2 MX races. She's an average to good 9 year old rider. I want to encourage her to race the scrambles and try to move away from the MX races. She's been ridin a Suzuki JR 80 that runs great but I can't find any modifications or aftermarket stuff to pump it up so I been lookin at the little thumpers. All the bike stuff I been readin says 200cc and less go 2 stroke. What's the deal?
