【Broad Compatibility】The clockwise threaded screw consist of 2 X 8mm and 2 X 10mm, while the counter threaded screw consist of 1 X 8mm and 1 X 10mm.Our motorcycle rearview mirrors are compatible with Kawasaki Z650 Z900 Z1000/Aprilia Tuono V4/1290 Super Duke/Duke 200 250 390 690 790/ YAMAHA MT-07 ect. Please refer to the Product details page for specific model years. 【Aerodynamic design】It's a wing when closed, and a rearview mirror when open. The aerodynamic rearview mirror enhances the appearance of the horizontal design, and its wing Angle of 25° relative to the ground gives it a linear appearance, ensuring that it generates downforce, which improves the grip and handling of the motorcycle, especially at high speeds. 【Aluminum Alloy Shell】Made of high-quality aluminum alloy casing. It has advantages such as high hardness, wear resistance, high temperature resistance, oxidation resistance, and durability. Even in various extreme weather conditions, it can perform well. 【HD Shatterproof Convex Mirror】Compared to regular flat mirrors, our convex mirrors provide drivers with a wider and clearer field of view. Eliminate blind spots and improve cycling safety. 【360° Rotatation】The 360° rotary joint can be freely adjusted to the desired Angle for a more comfortable and optimal viewing Angle, and can be freely switched between the rearview mirror and the fixed wing as required.
