I have the Velcro ones on all three bikes. Love them.

 

On a really long road trip I use a Cramp Buster style. I rotate it so that resting the palm of my hand on it keeps the bike running down the road. A little pressure to pass or on an up-grade, a little less on a down hill, and if I move my hand away at all, the Throttle closes.

 

This was my experience, too. I rode with it for awhile, didn't like it, and could never get used to it. I found myself having little unintended throttle surges when accidentally bumping it. I gave it to a friend and shelled out the money to put cruise control on the FLHR.

 

Left mine off one day after washing my bike and it drove me crazy not having it. I never thought I would miss it that much.

 

My previously enjoyed RoadKing came with the Kury ISO grips and have the throttle boss on both grips works great to relieve pressure and rest wrists on long trips .

I really liked them .

After a long trip the GF complined of sore Wrists so i bought her ....Throttle Rockers ...for both sides on her 1999FXR3 for like $17 on sale . they are really nice ,easy to put on with the velcro straps and really help.

 

I have the same Kuryakyn ISO grip set up, but with only the throttle boss on the throttle side. Really like it!

 

They are great for long trips. I have had 2 stolen though, just too easy for some a/h to rip em off.

 

Sad when someone has to steal a $12 part. And hardly with the whippin' one might get from the bike's owner.

 

The problem I see with the throttle boss is you can't get it out of the way, when riding in town. I think Kuryakyn is missing a good design idea by not putting a hinge on the throttle boss that lets the paddle flip up 90 degrees, so you can move it for stop and go riding.

 

I also have the helmet locks on the ISO grips as well as the bosses, extends grips a little but also give more area to rest hands on long trips.
Brenn after a while you don't even know it is there.
