Custom made, 3D printed ignition switch knobColor: BlackReplaces the factory knob that will more than likely have fallen off your bike while out riding.Fits right where the factory knob was and is secured with a #10 (3/16") machine set screw (INCLUDED!!) using a 3/32" Allen wrench / Hex wrench (2-2.5mm may work..?)New and improved design.
