I love the pointyness of the R6 tail. I plan on doing some scaffolding under it like the EBR bike.
The R1 fairing isn't my favorite, but it resembles the firebolt fairing, so I think that's what I'm going to use. I'm also going to do GP style exhaust. I want it to look like a modernized firebolt. I'm not about to make all new fairings, so using already existing stuff is what I'm resorting to. Also, one of my requirements in projector headlights, so the R1 is perfect.
