hey mate u are comparing a 140 and a 125 thats silly but the 140 is a better engine, the suspension on the 2 are about the same, more reliabe is the 140
i have the dhz 140 and its a great bike but id go the new pitpro 140xr or the pitpro 140 cause they have abit better components stock then the dhz but other then that pretty much the same bike but different stickers and colours the pitpro will always be abit more $$$$ then the dhz but
