Looking to upgrade or replace that stock steel axle nut on your Yamaha dirt bike? This anodized blue aluminum axle nut is a popular choice. It's CNC-machined from T6061 aluminum, so it's lighter than the original but still plenty tough. The thread is M20xP1.5, which fits a huge range of Yamaha off-road bikes like the YZ125 (1999-2022), YZ250/250X (1999-2021), WR250F (2001-2022), and many YZ/WR 400-450 models from the late 90s and 2000s (check the full list to be sure). It's a direct replacement for the rear axle shaft lock nut. The colored anodizing adds a cool custom touch, and it comes with a single nut. Just make sure you torque it to spec when installing. A simple, affordable way to add a bit of color and shed a tiny bit of weight.
