POLISPORT - 8151000001 - Disc And Bottom Fork Protector - '08-'26 Yamaha YZ450FX, YZ250FX, YZ450F
Rocks and roost don't discriminate between the fork legs and the brake disc, which is why Polisport pairs this guard to cover both at once on '08-'26 Yamaha models. The high-impact plastic shields the brake disc and caliper while the bottom fork guard protects the lower fork leg, and built-in air intakes keep the disc from overheating under hard braking. It installs without pulling the wheel and accepts oversized 295mm discs, though the disc guard only works together with the fork guard beneath it, so a full pair delivers full protection. Sold as a matched pair in black.
