We just received this 4 wheeler about 2 weeks ago. It's my son's Christmas present this year. My 8 year old son rides this around like it is nobody's business. My husband has it set at a safe speed for him and he has a blast! Perfect size for fun! Do not have any complaints!
This ATV-3125R is a good deal bigger, wider, and taller! Has big 16"tires, seems to be fast, the engine is bigger and rumbles more(its 125cc)and it seems to be able to haul my 5'09 180lb+ frame around without any struggle. This model is also a lot roomier, so you don't feel so squeezed up on it. Totally worth the cost!
