Developed for Hard Enduro, Baja, Motocross, and off-road. Suitable for all types of riding. Streamlined profile with increased coverage of swingarm mounting tabs. Large chamfered outside leading and bottom edges for maximum rock deflection. The replaceable wear pad works well for high abrasive conditions like mud, sand, and oversized sprockets. Redesigned wear pad mounting bolts with deeper recesses to reduce snagging and provide more clamping strength. Small diameter wear pad pins for added ground clearance (now strengthened for hard enduro and extreme applications). Fits standard and sealed chains. Includes new mounting hardware. Industry-leading plastic formula "RMS" (Return Memory System). Absorbs impacts and returns to center. Friction-reducing additives and UV protection to eliminate color fade. Used by championship winning race teams worldwide.
