I'm 6'1, 265ish lbs depending on the day. Looking to get a bike to tool around trails with my 6yr old on his CRF50, nieces and nephews on their KLX110Ls and my brother-in-law eventually. MAYBE some day, I would go to a track to just try it out and have some fun, but that's not the main purpose. I am a 100% newbie as my experience is limited to tooling around on the 50 and 110s as well as my neighbor's TTR-230. He is WAY bigger than me and had the rear suspension setup for bigger riders. I really liked the TTR230, but as I said, I don't know any different really for a full sized bike. I didn't get a chance to try and wring it out or anything either. I know I want a 4-stroke. Been leaning toward Yamaha or Honda. Reliability and comfort are important to me. So after all that....what would you all recommend I look at other than a TTR-230?
