6299 Premium ISO Contoured Throttle Boss Motorcycle Handlebar Grip Accessory: Universal Fit, Right Side Only, Chrome, Pack of 1

Top of the line product.

Works with the Kuryakyn 6240 grips. Reduces fatigue in holding on the throttle for long rides. Fit and finish is great.

Works well. I've done several hundred miles already. Very easy to install. But, it has to go with the Kuryakin ISO grip, which is also easy to install on a 2009 Vulcan. I thought of getting the smaller version of this (the triangular) because if you set it up high it can interfere with how you grab the grip, whereas the small one may not since you have enough of a grip left. This is about 1/4 (or a little less) the length of the grip. I set mine lower (it's very adjustable) and it's comfortable. I have a much more comfortable wrist ride with this. Even the cheap plastic ones that go over the grip cost some $10. Spend a few bucks more (I think I bought this for $15 or 17) and get this one. It's one-time expense and looks so much nicer.

An interesting alternative - safe and practical - to installing a dedicated cruise control device on the throttle. This particular accessory accompanies new ISO-grips and heavy-weight caps, to minimize the vibration from the handlebars of a cruiser motorcycle. My throttle boss was installed at my Kawasaki dealer during the first service mark (at 600 miles). The positioning needs to be adjusted to suit my preferred twist position; throttle-on can vary, rider-to-rider, especially dependent upon the rpm's desired for long-distance riding. The unit that came in needs to be repaired (slightly) - the rubber on the underside of the throttle boss is hanging-off a bit. This is not a biog deal, but an inspection of the part inside the box from the seller could have taken care of this. I'll have to glue it and hope for the best...

I installed this on my 2016 Road Glide Ultra with the Kuryakyn ISO Grips on 13" tall bars. Very easy to install, just remove 4 small screws, the throttle boss comes with longer screws to use. The boss has slotted holes so you can adjust to your comfort. It makes long rides easy as you can just rest your hand on the boss and maintain speed. Almost like a cruise control. It looks good with the ISO Grips, and I would recommend these to anyone.

Simple to install. I had to reposition it a couple of times before I got it to where it worked for me. It’s very easy to readjust. Just tedious to get where I want it. I installed this and the ISO GRIPS on my Victory Hammer at the same time. Big difference with the feel. I didn’t have the chance to try them out for long rides before the weather turned cold and wet for the winter season. But for the few rides I did get in I am very happy with the comfort and can’t wait until spring comes to really put them to the test on a long ride!

I've been using a plastic Cramp-Buster for a while, and really like the fact that I can loosen my grip on the throttle without having the throttle move when riding on long trips. I ordered this to match my Kury ISO Grips, so I would have a more uniform look, and a throttle assist that doesn't lose its position like the Cramp Buster (one bump and it spins around). Install was quick and easy... unscrew the 4 screws on the grip end-cap, put the Throttle Boss in place, and replace the end-cap using the included "longer" screws. It takes a bit of time to get the Throttle Boss exactly where you want it, but once it is set in the right position, you'll never know it's there! If you have Kury Grips, and frequently ride at a few miles or more at highway speeds (steady throttle position), then you'll really want to pick one of these up... Contoured (larger one) or the Standard (smaller one)... they make for less fatigue, which means you are able to ride longer!

The Boss looks great on the bike, but I have two problems with it, one major and one minor. First, It does not have full 360 degree adjustment capability. If you look closely at the photo, you will see the four circular channels through which the mounting screws attach. This means you get about 60 degrees of adjustment motion before it hits a hard stop. Then you have to remove it and there is about a 30 degree jump to the next channel. So of course my previously installed ISO grips had the mounting screw holes at just the wrong location to put the Boss at the optimum location for my use. So I can only position it too high or too low. Second, I would have made the paddle lever about 1/2 inch shorter, but that is a personal preference. Still, it looks very nice on the bike and is not completely useless as the lower position does give some wrist relief. If I could position it about 15 degrees higher, it would get 5 stars.

Typical quality for this brand. Fits iso grips like a glove. Comes with longer machine screws. Does it work? Not sure if it is stopping my hand from falling asleep but it gives me alternate ways to keep on trucking while using different positions and bring my hand back to the living. I do like the feel.

Great quality, easy install, takes pressure off wrist and grip for those long cruises. Highly recommended

EL único problema que le veo es que la posición ideal para mi queda justo entre dos barrenos de los tornillos, por lo que tengo que ponerlo, o arriba, o abajo...

Lo regrese porque no se adapto a mi moto

Quick delivery, nice it came with longer screws, haven’t got to ride yet but fit and finish feels great
