I had a Yamaha TTR-125 as a kid, and my little sister had a Honda CR100. My dad races enduros in the Northeast and usually has one or two KTMs in the stable. He has one of these for the street and loves it:
06 Yamaha FZ6
My dad doesn't want me to get my motorcycle license yet, and I see his rationale, since I'm from NY where people drive like morons and it's kind of pointless to bring one to UM.
