2009+ Yamaha YFZ R Rotor Guard. Completely redesigned from the top down, compared to the previous product iteration. We wanted to take a new approach to what a "wear item" should be after looking at what the industry currently offers. Our thoughts are, why buy two or three knowing they have to be replaced, when you can buy one and have the confidence it will last! This new rotor guard is manufactured from the same material as our legendary Axcalibar axles, 17-4 Stainless Steel for maximum corrosion resistance against those deep muddy conditions! But we didn't stop there! This rotor guard has been heat treated for superior strength and hardness to withstand the toughest conditions you can throw at it. No matter if it's rocks, roots, or ruts, it will keep your rotor protected and your brakes consistent for well beyond anything else out there! It utilizes oversized gusseting for improved rigidity, and counterbored mounting holes to protect the bolts from sheering off against rock strikes. Comes standard with grade 10.9 6mm bolts, but the mounting holes are oversized to 8mm for those that want to drill and tap their swing arm for the larger 8mm bolt diameter. Offered in Raw, heat treated stainless color (recommended), Semi-Gloss Black, or Custom Color of your choosing.
