The online parts catalogs don't have the '07's listed yet, can someone that has an '07 YZ450 tell me what the spring rates are? I thought I heard something about softer spring rates so I want to see if they do come with softer springs. It should say what the stock spring rates are in your owners manual.

I believe the '06 came with a 5.4 shock and .46 fork springs.

According to RT's info, the only one I've seen for an '07, they measured the forks at 0.48 and the shock at 5.5.

Thanks guys, I saw that Race Tech was listing them as stiffer than the '06's, that's why I wanted someone to look in their '07 manual to make sure.

My buddy's looking into buying an '07 YZ450 and I was hoping to be able to swap springs with him since he's a little heavy and I'm a little light for the stock setups. So much for that idea. Looks like I need to find somebody that has some '06 YZ250F springs, they're a little lighter than what's in the 450's.

Thanks again, sometimes all it takes is a little bump of a post to get a response, otherwise it gets buried.
