That is true, but the fully closed position has an impact on your wrist and arm position in many situations.

As stated above….It doesn’t matter if the throttle is rotated all the way forward or 90 degrees backwards it’s still the same amount of rotation as sad above(I’ve dealt with this with riders thinking if the throttle is rolled forward you don’t have to twist it as far). Take a marker and make a line on the edge of grip at 12 o clock. Turn throttle to wide open and see where line stops. No loosen and rotate throttle housing back away from the brake lever and do the same thing. It doesn’t matter how it is set up, a 1/4 or 1/3 turn throttle is the same amount of turning no matter the position the housing is tightened on the bar.

You're right that the distance of rotation doesn't change, it's always going to be roughly 90 degress or whatever it is.  

However, by rotating the throttle housing on the bar, you are changing the start and end points on for the 90 degree range. This influences rider wrist/hand angle in certain riding situations.      

If throttle pull is 90 degrees, then starting at 12, 3, 6, or 9 will all be the same feeling.  Just like starting at (1, 4, 7, or 10) will all be the same, 
But! Starting at (1,4,7,10)  will require the hand further forward/up for the same throttle % compared to (12,3,6,9).




 

Yep, elbow up or elbow down. Thats why people rotate it forward to help keep the elbow up.

I run a G2 quick turn throttle on all my YZ 2 strokes.    When i compare the amount of throttle turn on my YZ250 to my YZ450F, it is slightly more.   With the G2 quick turn, it is about the same as the 450.

I’ll look into them, I’ve also seen where some people seem the like that T-Rex throttle assembly

I have seen guys run the throttle housing with the pulley on the underside. Though they were doing it more crash damage protection, it could still possibly give you the clearance you need for the brake master cylinder.
