I remember going through all this 3 years ago; the engine in the RS (GS) is the same basic engine as the Aprilia Tuono and 2 cylinder RSV, the gearing (1 thru 5) is identical, 6th gear was removed to make room for reverse.
If I had the money and inclination, I think the 1135 kit and an advance in the cam drive (1 to 1.5 degrees) with stock cams would would be a nice setup in the Spyder, it would move the torque curve down, and increase the torque at the same time, while limiting the peak RPM by about 1K rpm.
We have to remember that the Spyder is basically pushing a barn door down the road, and to compare a trike (any trike) to a 2 wheeler is apples to oranges.. I read an article about a Victory Cross Roads with a Lehman kit on it that got 26 mpg, but the author didn't complain about the mileage, where in an earlier issue of the same mag, 29 mpg on an RT was bad. Wonder why.
OK rant over.
