A friend who had one of those BMW GS round the world type bikes had a plug in heated waistcoat worn under your normal bike gear - I suspect the Beemer might have an electrical system designed for lots of overpriced BMW accessories though.

Alternatively, my mother has a battery heated bodywarmer. The lithium ion battery is rechargeable and good for 6 hours at the lowest setting and about 2 hours if set on toasty.
