Condition: NewSpecial Feature: Brackets are designed to not rotate in the event of a low sideMaterial: UHMW-PE (ultra high molecular weight polyethylene), aircraft grade aluminumNo cut or plastic fairing modifications requiredFit Models: Yamaha2013 - 2021 FZ-07 / MT-07 / XSR700 This purchase is for a pair of frame sliders, rear axle sliders, front axle sliders, case covers, sprocket cover, and spool adapters for the models mentioned above. The sliders feature a new design of a complete solid puck without a hollowed-out center. This increases the strength and contact surface to about 30%. The bracket is bolted to the engine mount and the slider puck is bolted onto it. The brackets have four attachment points preventing them from rotating in the event of a low side. The material of the puck is made of UHMW-PE (ultra high molecular weight polyethylene), a tough plastic with good strength, wear resistance and dimensional stability. It is more dimensionally stable than Nylon and used in many industrial ball bearing and friction reducing applications. Compared to Delrin, it is softer but tougher. Delrin is harder but more brittle. It is an ideal material for frame sliders since it can absorb more impact force onto itself and therefore reduce the impact on the frame and engine. The slider pucks can be inexpensively replaced in case of a low-side. The rear axle sliders provide indispensable protection for your beautiful expensive swing-arm. For the front and rear axle sliders the installation is a simple bolt on with the bar going through the axle and one plastic puck on each side. The long bar and inserts inside the sliders are made 6061-T6 aluminum for strength. We use highest grade commercially available 12.9(177,000 psi in tensile strength) wherever possible. Rest assured that you are getting the best material commercially available. For our swingarm stands, frame sliders and please click T-Rex stands.
