Hi Glennd,
I purchased heated handgrips that cost me $76.00 from my local motorcycle dealership. Installation was ALOT more....$160.00, but hey, I sure couldn't have done it! I can't tell you what brand they are though. All the invoice says is "Hot Grips Stree Cycle". It was one of those things where you order something out of their store catalog that has to be installed professionally, you never get the unit handed to you in a box, so you don't see the product until it's installed. No box, no literature. Never even thought about it. So can't help you w/the brand, sorry.
I can tell you though, that they REALLY do help! Even though I live in sunny California, we get cold weather too here on the coast. I tried liners for my top-o-the-line leather gloves and that didn't help at alll.
I'd heard of heated hand grips and that sounded sooo nice, that money was no object. One cannot ride w/frozen fingers, right??
Ok, just wanted to share my experience. Hope it helps if you haven't already found anything to work for you in that area.
