BF010820-n Speedo sensor magnet bolt. M8 x 1.25 x 22.5mm

For custom builds using larger hardware, this Koso speedo sensor magnet bolt comes in an M8 x 1.25 thread with a 22.5mm length. It features a built-in magnet in the head, specifically designed to trigger a reed-style speed sensor for digital gauges. By swapping out a standard brake rotor or drive pulley bolt for this magnetized version, you get a reliable, high-strength signal source that won't fly off at high speeds. It is a professional-grade solution for universal fitment, providing a clean installation that looks like it came from the factory. This bolt is an essential component for anyone looking to add modern digital instrumentation to their custom motorcycle.
