Hayabusero, I think I have the only passenger backrest equipped Busa in captivity.
It would be fairly easy to cobble up a universal backrest to go on the Busa, but that would look like crap. I took a more expensive but far more pleasing way.
Corbin did not make a Busa backrest;I checked.
I like a backrest not only for a passenger, but for being able to use some of the low profile T-Bags for luggage.I also want it instantly removable without leaving any ugly brackets .I like the 1/2cu.ft. and the 1 cu.ft. T-Bags for a '96 Harley Wide Glide, since they are small but hold a lot.Bought a backrest from Corbin to fit the same bike, and got it in the cf leather to match the Corbin on my Busa. Bought an extra grab rail, but not really necessary.
Took the backrest, the bag and the grab rail to my wrench in Poway, who is also a machinist. Installed the grab rail, set the bag on the passenger seat in proper riding position. Measured the shaft on the backrest for length.(A pocket on the bag fits over the backrest, the bottom of the bag rests on the seat, and it attaches to the rail with straps for additional security.)
After checking the angle to find horizontal, a small flat area was milled on the top of the grab rail. The shaft of the backrest was shortened, placed on the flat area of the rail and secured with stainless steel screws from underneath the rail into the bottom of the shaft. A small brace was added for additional strength. Very sanitary.
When I want the backrest, I install the grabrail which it is attached to. When I want the standard grabrail and seat or the hump, I just put them on. The Corbin backrest is adjustable for rake, which is another good feature.
This all sounds a lot more complicated than it is. The project is probably overkill for most people, but it works for me.
