I'm not sure if this is what you are looking for, but this is what I have on my moto.
Thanks mate. \m/I'm no help to the OP, but a SBK tail will actually eliminate the stock seat completely and have a reinforced fiberglass or otherwise platform that you rest your bum on instead. It could be ridden on perfectly fine as is, but most will put a thin pad on there mainly to keep you from sliding around on a slick surface.
Unless they have changed recently, hot bodies is not a superbike tail.What about hotbodies? Looks like a sbk tail.
Shipping is crazy expensive, but probably one of the coolest looking I've found.
