Ok so I am looking for a bike to buy before winter and want to end up with a decent offroad machine with nice low end torque, and something that I can put alot of miles on before re-fueling. I have found a really good deal on an 03 ktm 250 sx. Keeping in mind that i'm on a budget, would it be worth it to buy that and slowly modify it with the ims tank, an offroad pipe, sprocket, basically all those goodies or just buy a bike more suited like an xr. The only worry I have is that the xr would take a lot more effort to ride in tight woods riding. Any input?
