I am a novice rider that just wants to have fun on my trials bikes 60 years old 137 pounds . GasGas came out with a 2017 School boy 125 steel wheels , steel forks and not a rieger shock . I can get one for $4500 new . I have a GasGas TXT Pro 14 300 that has more power than I really like and a GasGas2013 250 Factory that is dialed in . It is my primary ride so any other bike just adds to the fun . What are the different 125 s like and why not this inexpense Gasser ?
