Since buying my Kymco AK 550 I've been looking at finding out a way to NOT install my Gerbing heated gloves controller setup on this new bike. The AK 550 has factory heated grips so it makes sense that I shouldn't need heated gloves also depending if I can make the grips work by themselves. I do prefer to minimize what farkles I install and only install what I need to provide some feature not already available.
After much personal research on the options I concluded that I needed to be using handlebar muffs or mitts. With just the heated grips my hands were plenty warm when temps were down to around 27F (-2.8C) but anything below that my finger tips were not getting the heat and would start feeling, well, actually not having any feeling due to being frigid. Since I ride in temps that sometimes range down well below zeroF (below -17.8C) I needed more than just the heated grips alone.
I tried a few lower priced handlebar mitts. They were well insulated and would likely keep my entire hands warm at any cold temp but all of those suffered from the same major problem. Even with my lightest summer gloves I was not able to slip my hands into them when they were mounted on the bars without using another hand to hold them from being pushed off the bars. Kinda hard to do when one hand is in and the other hand needs help getting into them. Besides, that becomes a hazard should I need to pull out a hand for some reason while riding and then need to put that hand back in. Those also were a bit confining inside so would pose a problem operating all the controls on the fly. Those would just not work. I did read of one user who tried them and he put a stiff plastic panel folded in them to hold them open. I wanted something better than that since I wasn't going to trust any added plastic stiffener to stay put.
One member on the ST-Owners forum recommended a set that he has used and liked really well. He recommended the Kemimoto Universal Touch-Friendly Winter Gloves (handlebar mitts).
https://www.kemimoto.com/products/kemimoto-atv-mitts-motorcycle-gloves-b0106-00101bkThey have a phone pouch on top the right mitt with a water resistant zipper closure that you can operate a cell phone through the window. They also have a stiff foam rib that runs around the opening where you stick your hands into that does really well to hold them open. My AK 550 has a rather bulky handlebar cover and these easily fit over that so I would say these will fit on any motorcycle handlebar with or without a plastic cover. There is plenty of room inside to operate all the controls around my grips including the controls that my AK has on the front side, top and back side of the control clusters. I had no problems operating the brakes and all other controls with these mitts. For those with a DCT and a parking brake on the bars, my AK has a parking brake lever just inboard of the left grip, the mitts will likely have to be taken off to use that. I don't usually use the parking brake on mine but if I wanted to the mitts are easy to remove and put in a top case or saddlebag to use the parking brake lever. I went on a 22 mile test ride with them this morning with temps from 7F (-13.9C) to 10F (-12.2C) and I ended up having to turn the heated grips down from high to low since it was getting a bit too hot on high. To be fair I was wearing my TM PolarTex gloves but I'm certain I would be plenty warm at those temps wearing my summer gloves.
My gloves can slide right in without any problem. There is also a stiff rubber front guard on the mitts with a stiffer rib on the outer edge that keeps them more open inside.
I ordered these directly from the Kemimoto web site link above. It took 15 days to arrive. Kemimoto still has a 15% discount that pops up on the web page after waiting a minute or two.
I also do recommend these handlebar mitts for cold weather riding.
