Hi guys, I have a question regarding the differences (if any) between 450's from other manufactures (Honda, Kawa, suzuki. ..ect) I have always ridden Yz's, started on a YZ80 when I was 12 and had several 125 and 250's (all 2 strokes). I have been riding for 25 years and last year I bought a CR450 because I heard so many good things about it. The build quality was the best I've seen on any dirt bike, but I never felt comfortable on it. The ride seemed harsh, the bike was tall and thin and it just felt strange. I sold the bike after about 6 rides and now I'm considering trying another 450 this Fall. I'm wondering if I felt uncomfortable since I am used to riding Yamaha 's, or if it was becasue it was my first 4 stroke. Do all manufactures use the same basic geometry on their frames? I know some use a 'perimeter frame' design, not sure if that makes a difference or not. Also, in photos the KX, 08RM and CR looks like they all use the same frame.... Thanks.
