Gear Indicator: Any of you use 'em? I'm thinking of getting one, but im not sure if it's worth it. When i got used to my R6, i knew what gears i was in most of the time, and when i got the R1, i was having a little trouble at first since i was getting back into the scene, and since i dont redline it in 1st or 2nd, i usually just shift away without realizing what gear im actually in. Suffice to say, im not bad and down shift counting, more of the upshift, oddly enough
Exhausts: I dont know who to go with at all.

Especially since it's a liter bike. Arata sounds nice. I've always heard Akrapovic performs well on R1's. Damn near everyone uses Yoshimura. I've also been looking at just the cans from GYTR (Gangster Yamaha shit).
Frame Sliders: I'm getting carbon fiber ones by Philip Lockhart, but I dont know if I get the ones that mount near the engine, or the ones that mount near the back of the frame closest to the seat.
If i think of more things i'll ask. Gonna get a lot of threads out of me
