I would think that riders 6' and over would be more comfortable on the 450R. When sitting on it I felt like I was in more of a neutral ride postion compared to the YFZ. I'm only 5'10". On the YZF I felt like I was leaning forward to to reach the bars putting me an an awkward ride position. I think that alot of the riders that have the YZF might like that riding position. Given I'm not a racer, I like the neutral ride postion feel of the 450R. Hey, if you like the YFZ, this could be corrected w/ either a new stem and or taller handle bar clamp or both. I thought that the YZF was a little louder than the R, but not too much louder. No problem answering the questions. I just whish that everyone who ordered the new R had it by now so we could hear their input also. <FONT face=Arial size=2>
