Help with buying new grips

You cannot tell from my sig pic, but both of my grips are different.
I also have this weird device that is supposed to lock your throttle like a cruise control so that grip isnt even all the way on because of this thing. (I want to remove it) I am looking on amazon for grips but cannot figure out what I am going to need.

I am sure allot of you have changed your grips since you got your bike. What specific size or other requirements should I be looking for.

That is what I have on mine. Came with the bike when I got it three years ago. My only complaint is the foam is tearing, but I wouldn't be upset if I were to put the same thing back on it.

 

Mine are spider peak grips. Check out my build to see the look. Neat combo of foam and rubber, super comfy, great grip, relatively easy install (throttle tube took some dremelling)

 

Got these on 3 bikes, softish and grippy they are slightly thicker in the middle which i find comfortable. Progrip Rally 714



They fit standard 7/8" bars, one has bigger inside diameter to fit over the throttle tube. Which standard for most grips.
