makes riding any distance more comfortable! I LOVE this product. It's super easy to install and makes riding so much more comfortable. It fits ANY style handle bar and can be adjusted for each riders preference. I have cruise control on my '16 Street Glide and find that it's more comfortable to rest my hand on the throttle boss then use the cruise control. I recommend it for women who complain of their hands 'going numb' because they are death griping their throttle. Great product! July 5, 2016
This works great The Throttle Boss works great on my heated grips. Much less intrusive than other add on Throttle Boss's February 2, 2016
Gradually slips on V-strom stock grips Product operates more-or-less as expected, however there is not enough tension to maintain secure positioning on the stock handgrip of my 2006 Suzuki DL-1000. It is necessary to reposition the device after about 10 minutes of operation, since it gradually rotates downwards until it's no longer effective. This product would probably work better on thicker grips, or perhaps the space could be shimmed out with a piece of inner-tube or similar. (I have not attempted this, call me lazy.) I have a Kuryakyn "Throttle Rocker" which I've found to hold it's position much better. July 15, 2015
Handy doodad This gizmo does help hold a steady throttle against the return spring. Takes a lot of strain off your right hand. Will see how it holds up over time. So far seems pretty handy. May 4, 2015
Easy to use, but slips too much A good throttle boss needs to be thin and stay in place. Unfortunately this one is too thick to be really comfortable and simply won't stay in place. I thought the rubber strap would lock right onto my rubber grip, but it's too slippery. On the plus side, the rubber easily stretches around my 7/8 grips and the rubber hook works great. It's one piece and looks like it will last a long time. If only it stayed where I wanted it. November 12, 2014
Love this throttle boss. Unlike the larger ones this one is u Unlike the larger throttle bosses this one is unobtrusive. With others I was always afraid when coming to a stop that I would inadvertently press down on the throttle boss (giving max. throttle) at the very time I intend to brake. Not an issue with this size. Even though I have a "real" cruise control for long flat streches of road, I can use this throttle boss when I'm off and on the need for cruise. This is a great hand saver. I just rest the heel of my hand on the Kuryakyn Universal Throttle Boss and easily manage the road while not fatiguing my hand. I travel around the globe. Carry one of these with me to place on rentals. Usually walk off and leave on the rental though! November 1, 2014
