I'm looking for a new 24mm rear axle nut, sprocket side. When I look at the parts schematic on the OEM parts website, it appears that the part is integrated into the rear axle itself. This is not the case for my bike; it is a separate 24mm nut that is threaded onto the rear axle. 2011 Honda CBR250R 2AC REAR WHEEL | Babbitts Honda Partshouse Part number 3 to be exact. I'm a little confused.
