I am 15, 6', and 160 lbs. I am getting my first bike for trail use. I was considering the Yamaha TTR 225 but I have heard many negative things and have decided to look elsewhere. My price range is only $3000. The only other new bikes i could afford that I have found are the TTR 125L the DRZ 125 L or the KLX 125L. All of those seem a little small and i have been looking for something bigger. My local dealer has 4 used bikes that stood out. a 2001 XR200r, a 1998 CR 125, a 1995 Suzuki KMX250, or a Kawasaki 250 (sorry i forgot the year and make). Do any of these stand out as good first bikes for a pretty big guy? Could anyone tell me if I should go new or used? Four or two stroke? Thanks. - Ben
