I'm just going to put this out there.
I make a 1/5th throttle insert that works on the 600's, 10R, 14R
it reduces the throw of the throttle grip from 92' degrees of rotation, Idle to WOT... to 72' degrees of rotation.
a number of the 10R pilots have said it helps the carpal tunnel
I know it's difficult to do on the new 300. There is lots of extra plastic inside the throttle housing. LittleRed was giving it a go.
the ones I have are designed to fit Kawasaki throttle grip part number 46019-0001 and 46019-1095.
it may fit others as frequently a different part number just means the rubber on the plastic has changed.
If you want to give it a try, shoot me a PM and we'll go from there.
