I have an 05 YZ250 already valved and sprung for my weight. In 06 Yamaha went to the SSS suspension making it 90% speed sensitive where mine is only 30%. So how much better is the SSS stuff, should I look into buying it. If I do are the forks the same on 125s, 250s, 250f, 450f? How about the shock and linkage, is this stuff bolt on and go, what needs to be done?
