As far as I know most of the harley stock is the last generation. Some dealers may have the new micro wire, but I am not sure. The T-5 gloves are the new Gauntlet style micro wire and are great. There are a few dealers that sell Gerbings and not just the HD Gerbings gear.
If you go to the Gerbings web sight
Gerbing's Heated Clothing // The World's Warmest Clothing! you can find a dealer nearest you, and sometimes that would be a power sports dealer or different brand of Motor cycle Dealer such as Honda or BMW.
If you are Law Enforcement, they have a discount program for that.
If you are going to buy I would sugest getting the microwire clothing. It heats faster and you cant feel the wires in the heating elements at all.
As far as I can tell the HD brand cost as much or more than buying it direct from Gerbings. Also if you are interested in pant's liners, I would suggest that you spend the extra money and buy the Extreme armor heated over pants. They are easy to put on and take off. But not bulky. You only have to wear jeans or whatever pants you normally wear under them. Not that there is anything wrong with the heated pants liner's that they sell, but you have to put them on and then put your pants over top, and depending on the weather and rain you still might have to wear a rain suit or chaps.
You will see all of thier products on their web sight. The jacket liners are nice and I have one and I also have the extreme over pants and an extreme jacket. This stuff is warm and not bulky and uses thinsulate. It is warm even if you aren't heating it.
If a dealer near you doesn't have what you need in stock and you have to have it right away, "Like me" Ha Ha", then you can contact Gerbings direct at 800-646-5916, and they will ship it to you.
And No I'm not a saleman, I just think it is the best gear I have ever used.
I rode this afternoon the temp was 14 and the wind chill was 8 degrees and I was perfectly comfortable at 55 mph, The wind was gusting at over 60 mph and a constant 45 mph wind. So on the Highway the wind chill was probably below zero. You have to try it to believe it. If your going to any of the International Bike shows, they might have a Gerbings booth there. They do go to a lot of shows and such.Just a thought. Hope that helps with your question. I didn't mean to ramble, but I always do. "Gee maybe that is why my wife act's like she is hard of hearing" LOL "Ha Ha" Take care.
