Yes, it has the original SPK tail section. I had already purchased two full kits before the GP bodywork was available and after verifying through Jesse that the upper would fit the original belly and mids I just purchased the upper and the adapters. I am glad I bought the adapters, I would have spent a long time getting the spacing correct on my own. If you choose to use the stock fairing bracket you will have to fabricate a gauge bracket to relocate the gauges back and up slightly to allow additional space for your lowered clip-on locations. I also welded my steering stops to maximize my distance, still lost a bunch though, don't need it on the track but find the limits while moving in and out of the pits and in the garage.Is that the SBK tail and not the GP tail?
If you look closely you will see where I added two additional attachment points, one to each side where the upper overlaps the stock plastic tank shroud. I didn't like how loose that area was so I fabricated an aluminum tab that I attached to the tank where the rubber grommet was for the shroud that we have to cut. This area is tight now and does not move or vibrate at speed.
The hardware kit is a bit pricey but I understand why, there is a lot of R&D that goes into it and their craftsmanship is top notch. I have been in this game for a very long time and choose to do a lot of it myself because for one I can, I enjoy doing it and it saves me a bunch of money to spend on stuff I can't do or don't want too.
