My 8 year old is out riding his CRF70 and wanted some advice on his next bike. He wanted a KLX 100 but I thought it might be better and last him longer to get a CRF80. Is the 3 speed KLX more torquey/faster than a 80cc CRF. I rode a 2003 XR 80 and couldn't really tell if it was faster or just seemed faster because of being taller and 5 speed. Any advise would be helpful . . . Thanks in advance . . .
