How many of you lighten your bikes up? Any one know any weight loss keys and tricks? Is the end result noticeable? I see a lot of complaints about the weight of the new yz along with the bulk of it, seems like these issues can be addressed fairly easy. I'm sure more than just pro sponsored riders are in to it, just trying to get a feel for what people are doing. The lowered subframes and shaved seats have to be a common thing when you can shift the weight down on the bike.
