I'm moving toward riding my Vespa only! after 55 plus years of riding MC's.
I have a Gerbings electric jacket liner-it's pre-microwire version and google seems to be telling me that 200 is the bare minimum to not draw on the battery and 300 to run it OK and 400 amps is best. The actual jacket is 6.5 amps best I can figure out. I've always used it before on a MC that ran it fine. I do not use any other htd gear, just the jacket liner & I have a controller which never gets turned up to high. I run straight/fused from the battery.
I've found comments on other models, not my 300.
Whats the real story?
