I would find my grip tighten on the throttle when riding and would develop a right hand cramp but since using this simple, adjustable attachment, I find my hand is so much more relaxed and I can ride longer pain free. Very easy to install and adjust to meet your needs.

Fit my 2012 Truimph Thunderbird perfectly. My wrist is happy with this accessory.

Well, Granny's new mobility scooter is actually a raised three wheeler...very sporty and fast. This fit the throttle just great and relieves wrist stress.

I have a sport-tourer without cruise control.This device is pretty good for relaxing your grip while droning down the highway.However, it is nothing but "in the way" while riding the canyon roads that I love.It can be rotated to be out of the way, but you have to stop to do it safely.It's a tradeoff...

It works well on long straights. Be careful when sliding it over your bar end; I noticed I scratched mine because I twisted this on from the end. I've set this so that my wrist is in a natural position when cruising, a downside to this is that I've rolled on the throttle unintentionally on a turn more than once. I now take it off and only put it on if I'm doing a long trip with long straights.

The cramp buster is a simple piece of plastic that does the job of giving your hand a break and lets the side of your palm operate the twist throttle, on your motorcycle. It’s very very flexible, for easy installation. It’s easily adjustable to your desired position, by rotating it easily backwards. But when you rotate it forward, it tightens down on the throttle grip and turns the throttle. It works great for me and worth the price! Great for around the city or highway cruising. No more hand cramps!

Instructions are to slide onto the end of your bars, I have brush guards so went the open up and force on. Not that easy but they never snapped. I ended up put on the inside and at road speeds use my thumb and rest my fingers. I have carpel tunnel and find my hand gets pins and needles if riding a long way, Rode 100km today and had no problems except my thumb getting a little stiff =) When going off road I just slide where when I stand up I dont hit the lever. I will start with 4 stars as you just cant adjust riding along that well.

Does what it is supposed to. It adds a sizeable tab to the heel of your throttle hand so you don't have to use as much force gripping with the right hand. Instead of gripping and twisting, you can have a relaxed hold on the throttle grip and simply press down with your right hand heel. This is probably one of the best bang for the buck items you can put on a motorcycle. I've never had it slip or pose any sort of problem. Goes on and off easily if you wanted to move it between different bikes.

I still can't believe how easy it was to install, how well it stays on my bike's rubber grip, and how good it feels to my hand on long drives. I find it a bit awkward in the city but it's fantastic on open roads.The term "12 pack" in the description is misleading -- it's just one product. And that's all you'll need.

I purchased this prior to a 600-mile trip over the Fourth of July weekend. For $12, this product is amazing. I had virtually zero cramping or fatigue in my hand and wrist, and I normally experience that when riding locally for longer than 20 minutes at a time. Like others have said, I did experience some unintentional revving while at a gas pump, so be VERY careful when doing low speed maneuvers with the CrampBuster in place. To remedy that after my incident, I simply rotated it 180 degrees to make it impossible to engage until I was back on the Interstate. I had zero slipping issues, and my bike is a 2003 Suzuki Intruder 1500.

Works great, i used it under my wrist, along my pinky finger and with my thumb, helped me get across the US with out any wrist issues what so ever, riding a sports bike with a lower profile handle bar setting.At first it might be hard to figure out how best to get the most out of it, but I found out that it came pretty intuitively as I was riding a long and it isn't very hard to adjust,assuming you are not stuck in hard traffic, you can manage a bike with one hand and you know how to use the clutch if you cant manage to rotate it with just your fingers and not disturb the throttle position.

I'd bought this because I'd been having some problems with numbness in my throttle hand that would start about a half hour into any highway trip. I'm sure it was from the constant pressure of squeezing the grip and maintaining "twist pressure" on the throttle in a pretty fixed position for too long. I'd been thinking about making the purchase for a few months, but then I tripped outside doing some yard work and fell pretty hard, using both my hands on the ground to catch myself. Within a few days I started having severe symptoms of carpal tunnel syndrome in both hands. Numbness/tingling in my hands during the day that would pass if I would flex my arms and hands a little, but then pain/numbness/tingling while I was sleeping at night from my elbows to my finger tips that was so bad it would wake me up. Riding the bike at all brought on the numbness so fast I started thinking it wouldn't be so safe to ride until I got this situation addressed, but I went ahead and ordered the CrampBuster to see if it would help.The appliance is super-easy to mount. Positioning the device is hit or miss until you get a feel for it, and it's probably not a good idea to adjust it while you're riding, as the adjustment requires you to roll off the throttle in order to advance the setting. Since I only use it on the highway, I've found that I can make adjustments as long as there is no traffic behind me that would be affected by my suddenly slowing down. I roll off the throttle, tweak the CrampBuster, and wick the throttle right back up. No, I don't pull in the clutch because I don't have one - I ride a big scooter with a CVT transmission. Anyway, postioning becomes second nature pretty quickly, and I seldom have to tweak anymore. If you dont' need it, it's very simple to rotate it out of the way so that you don't even know it's there.Now, does it work? Okay, I was hoping for total relief of my numbness and tingling in my throttle hand before I fell and injured my wrists, but I'd have been willing to settle for enough relief to at least ride a half hour or so without the symptoms. I wasn't getting that. It was like the CrampBuster was putting pressure on exactly the wrong spot. When the numbmess would hit a scant 10 minutes into a highway ride, I could at least sort of hang my thumb off the device until the numbness would subside, but I didn't really have my hand on the grip then, and my fingers were pretty far away from the front brake lever if I should have needed to use it in a hurry. About a week after I bought and installed it, I managed a 280 mile day, but it wasn't fun. As time went on, though, the symptoms subsided, and I started being able to use the CrampBuster as intended. Yesterday I went about 300 miles, more than five hours in the saddle, using the CrampBuster almost the entire time. It wasn't until I got home and was unpacking that it occurred to me that I didn't have a single instance of numbness on the entire trip. I think buying it right after I hurt my wrists made me have some unfair expectations. As my inflammation subsided, the true benefit of the CrampBuster started shining through. It's definitely a great value and does exactly what I need it to do. Just have a little patience as you get used to using it.

Do not buy this assuming that it is a "cruise control" for your motorcycle, as that is not its intention. The best descriptor I can think of is that this is a throttle assistant: this helps reduce the twisting force of your fingers to hold the throttle open, and transfers that force to a downwards motion of your wrist. It is an odd sensation transferring your throttle control to your wrist, but it significantly reduces hand fatigue on long rides.Be careful the first few times you ride with this assistant. Adjusting the position of the device requires you to stop to rotate away from the rider (only rotates in that direction because of device design and functionality), and if you rotate it too far, you have to rotate it completely around the throttle to get it to adjust down. Also take note of tight left hand corners (as the handlebar moves away from your right side, the natural movement will open the throttle), so practice using this device at low speed in a parking lot before heading up any winding roads).As far as sizes are concerned, the standard size fits sport and standard handlbars, but I would recommend the larger size for cruiser (and oversized) handlebars. I tried the standard size on my naked motorcycle and it fit perfectly, but was too tight on my cruiser (felt like it was going to break if used).
