Hey all - wanted to get your opinion. My son who's 14 seems ready to move up in bike. He's currently on a TTR125LE. I consider him an intermediate trail rider having run through all the route path of bikes since he was 5 (crf50>crf70>crf80>ttr125le). He's about 5'9 and 140. I've had him sit on a few full sized bikes, but they seem just a little to big for him still. I don't want to put him on anything that won't be fun for him. I was looking at the CRF230F and bikes in it's category, but they all weigh a ton and I feel like I'd rather put him on an older KTM 250. But then I'm concerned about putting him on more bike than he's ready to safely handle. What do y'all think? What's other bikes should we consider?
