Buy a 2-Smoker

I've got a 05 yz450f and a 91 cr250 and I love the way my cr rides. It's an animal! It would dust the 450 around a tight track. So my advice is if you're man enough and willing to put your life on the line - get a 2 stroke. I love the 450 because it's easier to ride, but sometimes that just aint cricket.
