Yamaha Motor Co., Ltd. 806-25711-00-00 Brake Disc

The Yamaha 806-25711-00-00 Brake Disc is a hardened-steel, solid-disc rotor designed for caliper-based braking in Yamaha snowmobile systems, providing a durable friction surface for stopping. This genuine Yamaha replacement fits vintage models such as the SL338 and SS338 (late 1960s–early 1970s) and is an OEM brake disc that mounts in the brake assembly to interface with calipers. Designed to convert kinetic energy into heat for controlled deceleration, it offers heat resistance and reliable stopping performance in snow conditions. Common replacements include Yamaha 806-25711-01-00, 806-25730-00-00, and 806-25740-00-00.
