Description

The SP1 Defender Wearbar (Part Number: WB-000-659) is specifically engineered to enhance the performance and longevity of your Yamaha SnoScoot 90″ snowmobile. Crafted with a 7/16″ carbon steel host bar, it features a flat top design that effectively prevents bar roll during aggressive cornering, ensuring stability and control in demanding conditions. The wearbar incorporates high-quality yg13 tungsten carbides, which deliver maximum tensile strength and extreme durability, reducing chipping and extending the life of the wear surface. The 90-degree carbide angle into the pocket creates large cross sections, providing increased strength and wear resistance compared to traditional designs. Designed with 1″ carbide segments, this wearbar allows for some flex in the ski without compromising carbide adhesion, maintaining consistent performance over time. The product is engineered and test-fitted for a precise fit on your snowmobile, enabling easy installation without modifications. Chamfered ends help minimize catching during backing up and unloading, while extended studs accommodate ski skins, adding versatility for different snow conditions. All necessary fastening nyloc nuts are included for secure attachment, and the carbides and wearbars are finished with a black rust preventative coating to resist corrosion. The hardweld contact area of the host bar enhances durability by increasing the depth of contact, improving longevity. Additionally, the wearbar is less damaging to concrete and asphalt surfaces, making it suitable for various terrains. Ideal for snowmobile enthusiasts seeking a high-performance, long-lasting wearbar, the SP1 Defender Wearbar combines robust materials and thoughtful design to deliver reliable service season after season.
