my brother is 14 years old 180cm tall and 70kg. he will be just riding around on a farm and maybe once a year on a mx track. he had a Chinese hunk of junk that we got rid off when my parents bought him a cr125. but the bike has too much power and requires to much maintenance and is a highly strung mx bike not a toy. anyway he needs something with a bit more controllable power and light as he is very weak and struggles to lift up his cr125. thanks for the help!!
