Hi everyone, My name is Derek and I need some opinions. I am 20 years old, 6 foot 3 and weigh around 185 pounds with gear on. I currently ride a 2002 YZ125 but recently I have been questioning it. I owned a KTM 125sx when I was 15-16 and I absolutely loved it but the 125 doesn't feel the same to me anymore sadly. Maybe because before when I rode one I was around 130 pounds and not so tall. I only ride on wide open trails (power lines) and in my backyard woods with some small 30-40 foot jumps. The YZ has a few upgrades to accommodate me like resprung and revalved suspension for my weight (race tech) a full fmf system, higher pro taper bars and some other small things. What i dont like: it struggles up hills Lots of clutchwork in the woods and around turns no engine braking (I loved the engine braking of my 150r when I was younger, I felt like a better rider on that little thing) pin it or no power at all What I do like: Lightweight, easily maneuvered Sound (obviously) Smell Ease of rebuilds Am I too big for a 125? I will probably gain another 5-10 pounds in muscle over the next few months btw (lifting). I think I want a four stroke. It will only be ridden from late April to late August (when I am home from college). Should I get a 250f, 450f, or quit my bit*hing and ride the 125 harder? Thanks in advance everyone. Any other questions I need to answer before you can give me your opinion I would be happy to answer.
