I use the $10 throttle rocker and no numbness........

 

+1 on the nostalgia rubber grips and the cheap throttle rocker. And surprisingly, riding w/o my watch on helped as well!

 

Throttle rockers are great\\; I love 'em, but you might also want to examine your bar setup. When you're in the riding position take a moment to see if your wrists are straight. If your hand is tilting up or down relative to your forearms,&nbsp\\;you can upset the nerves in your wrist. Sit the bike up straight, loosen the bar clamp slightly then try rotating the bars to see where your hand is most comfortable. If you find a spot you like, tighten things up\\; check the lock-to-lock turning to make sure you clear the tank then take the clamp bolts out one at a time, give 'em some blue locktite and torque 'em down. (Don't skip the locktite step. Trust me. I know.)

 

I put on&nbsp\\; KYakyn ISO with the throttle boss thingy hoping to find a a solution to the same problem. They have helped 30%.

Are there any other grips out there besides the ISO's that have an integrated throttle boss? Just wondered...I know the plastic paddle is available (also at www.throttlerocker.com) if you have others, but you know...

 

Kuryakyn ISO grips with throttle boss here as well.

 

I like the SAC leather grips from www.coolsac.com. They are padded and a larger diameter. They do not get hot or cold and decrease vibration. You can get designs (eagles, skulls or whatever you want) and can be color matched to your bike. I miss the ones on my 06 and plan to get another set for my 09. A throttle controller is absolutly needed for long rides. Ulatra has cruise control so that is not an issue for me.
Looke at SAC grips.

 

My problem solved with shorty Gel filled gloves.

 

I found by tightening the throttle screw snug reduced the numbness in my hand a bunch

I have Performance Machine grips and got my friend to put on his too. His numbness went away. Comfortable for me.
