KAWASAKI NINJA 650R 2009-11 WOODCRAFT FRAME SLIDERS Note: This slider kit requires cutting holes in the bodywork for the pucks. This allows us to make the sliders as strong as possible to ensure that they are able to do the job of protecting the bike should you need to use them. Patent pending design features a slider puck that can be replaced with one bolt. What makes the Woodcraft design unique is the perpendicular attachment bolt for the puck. Because we do not have to hollow out the center of the puck, we can leave the sliding surface of the puck solid.ovides 48% more plastic to slide on, dramatically improving puck life. The side mount also eliminates the hassle of trying to dig out a puck replacement bolt through a distorted hole. This provides 48% more plastic to slide on, dramatically improving puck life.
