Just some motorcycle paddock stand spools / bobbins that you can fix onto your swingarm with 2 x M6 x 25/30/35 screws with cylindrical head. They look like the Evotech Performance model. It`s a perfect fit for an Aprilia Rs 660 / Rs 660 Factory / Tuono 660 / Tuono 660 Factory or to any motorcycle that has an M6 thread.
