Essential for properly securing specific models to your Mojo Moto Hauler. Motorcycles including KTM/Husqvarna/Gas-Gas 4 Strokes as well as various Beta models have frames that curve up in the rear, which causes the rear end of the bike to dip down as you secure the Footpeg Retaining Shafts. This Wedge accessory counteracts that movement and ensures proper stability of your motorcycle on the Mojo Moto Hauler.
