Havin' a real hard time choosing a new quad. I used to own a Honda 250r. Man, I loved the acceleration and stability that thing had. Sold it 10 years ago, 10 years! Well, I NEED a new quad. Was thinkin' KFX 400 but this new YFZ 450 sounds like it will have the acceleration and stability that I loved about my R. So, how does it compare to a 250r? Or will a KFX 400 satisfy me. $5000 and reverse on the 400 is pullin one way, speed, looks, handling on the YFZ is pullin the other way. $7000, ouch! I will probably end up gettin' the YFZ. I have heard that a YFZ pulls like a 2 stoke, some even joke, calling it a 3 stroke. I always thought 4 strokes were "dumpy" in there power and handling. Thank for any replies.
