Which one should i get??? a WR250 or YZ250F

i have a CR125 and when i ride trails with my mate who has a KX250F its much easier for him on the 4-stroke so yes the YZ will do fine the top speed is about 85.If u want a enduro 4-stroke get the CRF250X otherwise go for the YZ250F.For track and trails.The only problem with the motocross bikes is that u cant keep the gas open for too long but that will be the same even better then your 125.Why dont u consider a 450 cause the 250 is the same as the 125 arnt u bored of it and u wont grow out a 450.

You will get very lazy drivin a fourbanger in the woods. A 2 smoker and you would have the adrenaline pumpin trough you. A yz250f would hold up fine just if you have alot of money its grand and the speed would be the same. the wr250 would have a lot longer engine life as its made for enduro and road uses witch yz250f is made to be looked after ever few hours racin. Like my friend races a ktm sx250 and his dad races a exc200 the exc witch is a endruo road bike can go the season with out been rebuit but the motocross sx has to be done at least twice in the year. But they are pro racers. Also if ur gettin a fourbanger second hand always make sure it has been rebuilt cause it will cost u a bomb to do if it has not.
