Thanks for any advice

Well _JOE_ I appreciate the lone reply! :)

The other choice would be the TTR230 - I guess more of a trail bike? I'm torn between those 2 choices.

Anyone else?

Thanks all! I've just got to decide on the flavor now - 2 stroke or 4.

whenfoxforks-ruled - I had a minibike when I was really young - my dad used to call me Brad Lackey Jr. It was years and years later that I actually learned who Brad was.
