I'm sure it couldn't hurt adding these if you were jumping a lot. Along with the the frame braces. I was wondering if the frame has had structual improvements made. I guess I could look up the frame part numbers of the previous years to see if the frame part numbers match. I'm mostly riding tight trails, desert, and crawling around over some rocks, so I'm not sure if this is something I need to worry about. Sounds like this modification was highly recommended on the earlier generation models. I figured someone out there may know if this is needed.
