So, right beside the mx track I go to is a go kart/supermoto track. I'd like something just to mess around on, and don't know what to look for. I'd like it to be not a full size bike. I've seen some crf150, and ttr125, but the crf is kinda expensive($2000+) in my area, and I've ridden my friends ttr125, and it was lacking in power. So, I was wondering if u can have a 2 stroke motard. I know it's probably a stupid question, but I'm new to motards. Also, how does a ttr125 w/ big bore do? Or the klx140? Do they have more power?
