It's time for a new bike. I'm 17 average height and weight and I've been riding a honda xr 250 for 2 years. I don't ride too much my xr 250 I'm always riding my fathers xr650 (with wich I do some enduros here in portugal) I love the power it's got but the bike is just too heavy and a bitch too start. I was thinking how whould a ktm 250 sx compare to the 650? I have also thought of the ktm 125 sx but it seems too weak or am I wrong? I'm also thinking of doing mainly mx but i'll also be doing some enduro for fun (with my father) thats why I think an sx will be the most appropriate model! It's kind of confusing to buy a bike these days with the 4 stroke revolution n all. Everyone says that the 4 strokes are clearly an advantage but bubba , carmichael , chad reed , grant langston.... all of them are still using 2 strokes. I love ktm and I have great prices from them and I want to stick with them. plz some help! Thanks in advance
