Been wearing Olympia gel gloves as well. Never looked at them for reducing vibration, but they are simply comfortable. Try several gloves...you will know right away when you have the right glove.
You're riding a Harley and as someone said to me (when I asked about the decel pop on my bike), "learn to love the things they do", or get a Honda.
There isn't a motorcycle in the world that doesn't vibrate. A honda doesn't vibrate like a Harley, but it has a high frequency vibration, especially at higher speeds. Spend a few hours on the interstate at 100+ mph, and when you stop, you have a buzz running through your entire body. Nerve damage or other ailments, especially in your wrists, can be exacerbated by vibrations - low, like Harley, or otherwise.
