I'm very new to dirt biking but I want to ride technical trails, with uphills, wet roots, loose rocks etc. On forest roads as well which is why a pure trials bike is not great for me. The key factor is light weight since I want to be able to maneuver the bike around stuff. I have no desire to go fast. I'm 5'8" 150lbs The ttr125L seems perfect because its a 4-stroke for the slow stuff and is the lightest of the small trail bikes. Its obvious that I won't be able to ride every trail I try and I have absolutely no desire to push/pull around a 250lb+ bike. Especially if its on an uphill! Everything I hear or read says the ttr125 is a girls/kids bike that isn't suitable for an adult male though So my question is where will I notice a problem with it? I just can't see wanting more power on technical trails where I'll just spin and I absolutely do not want anything heavy. Maybe I am missing something here though?
