Crate weight dry on my 2010 M8 SP was listed at 464 I believe. I recall the M6 was actually a few pounds more for one reason or another. Not sure how realistic these weights are. Didn't get a chance to test it. When it comes down to it, it doesn't really matter though. Once you pack on a gas rack, extra bags, you, and all your gear... every sled is going to be way different once it's on the snow.
