Hey guys I'm tossing around the idea of buying my son a mini pitster utv. He is 7 years old and my daughter is 3 my idea is by the time my son is done my daughter will be old enough to drive it. My biggest thing is like everything I would want to modify it, my end goal would be to make the machine race worthy even though there are no races in Utah I would like to get my son to really rally the machine. I'm looking for any info on modding these little bikes. Or your thoughts on the bikes themselves. Good or bad thanks guys
