I am new here so whats up. I just got back into dirt riding after ten years. Started riding Harleys when I was younger. Still do. I got myself a 04 xr 250r. I got my son who has never been on a bike before a 05 crf70. I hope I did not go to small. He is 10 years old and about 80lbs. I have not given it to him yet. The dearler said he would let me bring it back and get a bigger bike if I wanted. I just do not know. He is also 4' 9". What do you guys think. This is the bike the dealer told me to get. He told not to waste my money on a 80 and the 100 would be to big.
