The 2015 R1 has a special set of frame sliders with a brand new puck design just for this model. The frame on the right side sits flush with the bodywork and there are a number of electronics right against the bodywork on the left side, making the sliders particularly important. Our special new pucks have tapered edges - giving the protection you need while making the puck much more likely to slide over an obstacle as opposed to catch on it. We really like this new design! As with all our slider kits we have maintained our patented 2-piece slider design, making these the most durable sliders on the market. Our perpendicular mounting bolt allows the slider to be solid rather than hollow (like other sliders) which provides nearly 50% more material on the road and easy access for changing pucks after a fall.
