Mv Augusta steering nut tool. Will fit Mv Agusta Brutale, Mv Agusta Brutale 910, Mv Agusta F4 1000, and Mv Agusta F4 750. This tool is the only way to remove the nut when you are greasing the stem bearings. It is also good to periodically make sure it is tight. Because it is aluminum, the tool is light weight, and will not damage your bike parts, but will last a lifetime! This tool is brand new. A must have tool for anyone working on a Mv Augusta! This tool is not made in China or Hong Kong. It is professionally made in the USA on the state of the art CNC equipment with 100% quality inspection.
