Gerbings to a wr250x
It was 28 degrees F this am & I & 10 others went on a 250 mi DS ride here in North Florida. Half miles was easy in the woods/dirt. The rest, doing short high speed runs to the next trail just down the county street.
Just wire the two eye connections to the respected battery terminals & plug in your heated jacket/gloves.
All day I was warm & cozy.
Don't know what the wind chill factor was & don't care. There were a few who had no electric heating clothes. Some used the chemical little bags in the gloves & boots. Some had 5 & 6 layers of clothes & some quit early.
Just for the record my mpg were 71 & 72 on the two tanks.
The Gerbings are a little pricey but I get to keep riding all year long.
