SP1 Defender Wearbar for Yamaha Mountain Max and SX Models – Part WB-000-640

The SP1 Defender Wearbar (Part WB-000-640) is engineered for high-performance snowmobile applications, specifically designed to fit various Yamaha models including the Mountain Max, SX, Phazer Mountain Lite, and SRX 700 series. Crafted with a 7/16-inch carbon steel host bar featuring a flat top, it effectively prevents "bar roll" during aggressive cornering, ensuring stability and control in challenging terrain. The wearbar’s carbides are made from YG13 tungsten, providing exceptional tensile strength, hardness, and resistance to chipping, which significantly enhances durability and extends service life.
The unique 90-degree angle of the carbides into the pocket of the runners creates large cross sections, further improving impact resistance and wear performance. The 1-inch carbide segments allow for flex in the ski without compromising carbide adhesion, offering a balance of flexibility and strength. Engineered and precisely test-fitted for easy installation, this wearbar features chamfered ends that minimize catching when backing up or unloading, reducing potential damage and ensuring smooth operation.
Additional features include extended studs to accommodate ski skins, all necessary fastening nyloc nuts for secure attachment, and a black rust preventative finish on carbides and wearbars to resist corrosion. The hardweld contact area of the host bar increases longevity by providing more depth and wear resistance. The Defender Wearbar is less damaging to concrete and asphalt surfaces, making it suitable for trail riding and other surface interactions. Overall, this durable, high-quality wearbar offers reliable performance, easy installation, and enhanced wear resistance, making it an excellent upgrade for Yamaha snowmobiles that require increased durability and stability during demanding rides.
