Nice update

Much nicer than the original smaller version. Takes a little getting used to, but once you have, the extra surface area works much better than the older version.

Throttle Boss

Very easy to install on my Gold Wing. It stops the occasional cramps of the hand. It really is worth the price. Great decision of purchasing this product.

What a difference!

Purchased/installed these for both left and right grips prior to a long trip. Although I read great reviews on them, I wasn't expecting much of a benefit. I was wrong- they are fantastic and made a tremendous difference in comfort. They look great and I highly recommended them!

Contoured throttle Boss

I replaced my old Throttle Boss with this new Kuryakyn Contoured ISO-Throttle Boss and love it. Easy to install, much more comfortable than the old one. Another great product from Kuryakyn.

Great Addition to "The Ride"

When I bought the ISO Grips I also added the throttle boss. It totally relieves any hand numbness from a long ride and allows throttle control with a push of my palm rather than having to hold the grip...much nicer on the wrist over time. With small amount of use I wonder how I made out without it. This is a solid billet aluminum bit that is made for the ISO Grips and it works and looks great. Get yourself one and be happy!!

Don In San Diego

I Replaced The standard ISO-Trottle Boss with The Contoured ISO-Throttle boss. Much more contoured. Fits your hand better and very comfortable on long trips. I ordered Two thinking one fits the left and one fits the right. The Throttle boss only fits the right hand grip. No problem. Attach the right on to the left grip. And now you have one to rest your left hand. Just slide your left hand maybe two in. to the left. Buy and you will love em.

Great product!

The throttle boss fits perfectly on the Kuryakyn Iso-Grips I purchased a few weeks earlier. I've used it on a couple long rides and was very pleased with how comfortable it was and it definitely made the rides more enjoyable. It took a little trial-and-error, but I finally found the perfect position for it and it doesn't interfere with driving around the city.
