I like to ride all year. "If I'm not slidin, I'm ridin" is a common phrase I can tell anyone as they pass by, astonished I'm still riding into the colder season. At 20 degrees, if there isn't ice, I can be found on my bike, starting it up to make my way into work or wherever I happen to be going.
Heated gear, even gloves, can easily go over 150.00 if you don't already have the heat controller.
Then one day, I was walking through Menards, a hardware store for those who don't know, and spotted a $15 dollar 12 volt fleece blanket that you could plug in. Little did they know, I would cut this blanket apart to get the wire out to use for something else.
This is my thermal insert, made by Tour Master. I sewed additional fleece at the ends of the sleeves, because it just wasn't made long enough for me, and the fleece fixed that part. Now that it's getting into the low teens and single digits, it's time for another weapon, something a little warmer than I can make myself.
This is the lot. Somewhere near 30 ft of 12 volt warmliness, just waiting to be added, strategically, to make your cold weather riding more tolerable. What you don't see is the 30 minute timing circuit that comes with it. I just cut that off and added the wires again, soldered, complete with shrink tubing. The circuit is only for shutting off the blanket after 30 minutes and you would otherwise have to press the button for another 30 minutes of heat. I just spliced in a connector that I can pull out and push in as needed, to disconnect the power. You can make an inline switch if you like, I just mounted a plug to my bike to plug it in.
Another appealing feature about the draw of this system is approximately 40 watts. That is very close to 3 amps. I have a 28 amp alternator on a 1991 ST1100, so there can't be a lot of accessories to tax the available power.
