When my friend bought a suzuki 450,he actually went to the dealer and told them he wanted the fastest 450 they had.They had the 450R,YFZ,and the 450 suzuki.They told him the suzuki was the fastest.He bought it.First time he raced a stock YFZ,let's just say he was pretty upset.Yeah,the YFZ beat him.The suzuki beat the YFZ off the line but the YFZ reeled him in and went by him.I've rode all the 450's.The YFZ does feel like a suzuki but the YFZ is faster.I also like the 450R.I actually like all of them.
