Hey I'm new to this forum and I've been in moto for awhile and I've done my research on all the bikes. The bike I race right now is a 2001 Honda CR125 and I love racing it but its time for a new bike and I'm looking at getting a newer bike 2010 and up. I've been doing a lot of thinking about going 4 stroke or staying 2 stroke. I really want a 2013 kawasaki KX250F or KTM 150sx. What are your guys thoughts on the best bike for me? I weigh 170 ish pounds and I'm about 6 feet tall and I'm 15 years old. there's the bike I ride now.
