Nice

  Posted:

Wife loves it!!!!

  Posted:

It works and is good, but I liked the contoured throttle boss better

  Posted:

A definite must have!

  Posted:

Work's well and a lot less fatigue on the longer trips!

  Posted:

Nice match to the Right side Throttle Boss that came with my grips. Makes the bike look balanced.

  Posted:

It is like a hand rest. They are great

  Posted:

Very useful part I wish I could adjust them a little more

  Posted:

Does its job.

  Posted:

Awesome purchase, I don't have to grip the throttle all the time or use my cruise control as often for my hand to be comfortable. I'm thinking about buying another one for the other side just for aesthetics and maybe a little comfort.

  Posted:

Just another palm rest for the left grip to balance out the look.

  Posted:

The product is good.

  Posted:

love it.

  Posted:

These little guys rock! Great for trips or just around town. They really add more comfort to any ride.

  Posted:

Good Product. Works as advertised- Great people to do bussiness with.

  Posted:

Really helps on the long rides very little cramping of the right hand.

  Posted:

I love the Throttle Boss with the Iso-Grips. I installed them on my 2009 Heritage Softtail. It gives your hand a break when your feeling a little cramped on the long ride

  Posted:

this is the 3rd time I bought this items.I used them for gifts.

  Posted:

Best thing so far for allowing my right hand to relax on long trips -

  Posted:

Worth the money. Doesn't do a whole lot for me though.

  Posted:

Great product!!!!

  Posted:

Looks good with the Iso Grips and helped alleviate some of the numbness in my throttle hand as I can now adjust my grip without slowing down.

  Posted:

A "must-have" when installing Kuryakyn ISO grips. Greatly reduces hand fatigue and looks great!

  Posted:

perfect addition to my 2004 Roadstar. easy to install too.

  Posted:

Works very good but you have to set it correctly or it gets in the way whilr braking.

  Posted:

Really helps tired hands and relieves the numbness! Very comfortable.

  Posted:

i love it kuraykyn is good stuff

  Posted:

Great little invention. Great addition to the ISO grips. Great looks and works like a charm.

  Posted:

Excellent - influenced others to purchase.

  Posted:

Easy install, no wrist fatique on longer trips.

  Posted:

Great addition to the Grips.

  Posted:

A must on long trips.

  Posted:

The ISO throttle boss also works just fine.

  Posted:

A nice addition to the grips.

  Posted:

Love them. They look and feel great. I opted not to install myself and chose to have the dealer do it.

  Posted:

I should have bought this before the ride to Sturgis! The boss is simple to install and adjust, and is extremely comfortable. You rest your palm on the boss for those long cruises, and let your fingers relax. I thought it might get in the way during in-town throttle action, but it doesn't at all.

  Posted:

I love em! Great feel & looks.

  Posted:

Excellent product. Look great and very comfortable.

  Posted:

Pretty useful, especially on long ride!

  Posted:

The Kuryakin Iso Throttle Boss is a nice looking and handy addition to your grips. If you have Iso Grips on your bike already, all it takes is four screws (included) and about ten or fifteen minutes and you have a matching accessory with purpose. I use it as a hand rest, and also as a cruise control. How is it a cuise control you ask? I adjusted it so that it is level with the road at 60 MPH and all I have to do is rest my hand on top of my grip and rest the heel of my hand on the Throttle Boss. Just the weight of my hand on the Throttle Boss keeps the grip rolled back and I can cruise hours with little strain! The only downside to the device is my first Throttle Boss started peeling chrome after three years so I had to get another. But they are a good value, so the new one is on my V-Star now.

The Kuryakyn throttle boss has performed well so far. I like the look of the throttle boss paired with the Kuryakyn ISO grips as well as how it feels on my palm. I had a much larger throttle control device prior to the throttle boss, so I do notice the differance in size with the Kuryakyn being smaller. But, the Kuryakyn throttle boss complements the grips and makes the two look as one piece. Very easy install and the quality seems to be as good as the grips. By the way, if you don't have a set of the Kuryakyn ISO grips, get a pair, they are very comfortable!!
