Installed on my 2012 GoldWing. Also installed Kuryakyn ISO Grips for heated grips! It was smaller then I thought it would be, but wanted to assist on those long rides gripping the handle bars. Gave it 4 stars because of size. Install was easy and it looks good.

This helps to prevent that pesky hand cramping. Be mindful of where you set it since you get comfortable and then you see those blue lights in your mirror.

I really love this item. It really does take the fatigue off your hands when riding and you're not using cruise control. Easy to add on to the clam shell grips. Get some weighted ends to really give your bike a great look.

Great for long rides and when turning on the cruise control isn't practicable.

A must for the matching ISO Kury grips. Felt a significant amount of relief in my right hand because I no longer had to maintain a constant and tiring force on the thin factory grips. Prior to this, my hands could become cramped, tingly, painful, or all of the above while riding about. Now the just weight of my hand/palm keeps the bike going without effort.

The throttle boss is a great addition to the grips. It really comes in handy when riding in a group and the cruise control doesn't work due to the varing speed. just lightly rest your hand on the grip and the boss fits your palm and then it's just wrist action to control the throttle

This has got to be the best piece of add-on I have added to our bike. What a difference it really does make. We just completed a 945 mile trip and not once did my hands get tired. Adding the Throttle Boss to go with the grips does make a world of difference. If you havent bought one, then I would seriously have you go and make the purchase of one of these sets. I really dont think it would matter if you had the heated grips or not. These grips are GREAT!! Thank you Wingstuff for having this in your inventory..

This is a great add on, along with Kuryakyn Iso slide over heated grips. I also installed rings on each end.
This is a most for long hauls or even short trips, All together they do make a big difference. Numbness in hands are gone.

I installed this with the ISO grips for OEM heated grips. Between the grips and the throttle boss it sure has helped the thumb cramps I have been having. The throttle boss makes much easier to rotate and maintain throttle position for those times you cannot use crusie control.

Just installed this along with the ISO grips and I love it! When you get this adjusted properly the heel of your hand does all the work My fingers tend to fall asleep and I have to shake my hand out, from squeezing the grips all the time Probly carpel tunnel.
