Since I've had good luck with
them in the past and they're readily available, I usually
use Symtec heated grips. They come with either a
toggle switch or a round rocker switch. The motorcycle
version is good because it has different heating elements
for each side since the plastic throttle tube and the bare
metal of the clutch side conduct heat differently.
The best price I've found is
Finding the OEM heated grip power
And here's a PDF of how to
install the Symtec heated grips with a BMW heated grip
switch. Most of it is applicable to other brands as
The high heating elements on the
Symtecs are pretty good but sometimes, in colder weather,
don't put out enough heat. The solution to this is to
hook up both heating elements to a variable power supply.
(You probably don't want to run both the high and low
elements at 12V as that would probably be way too hot and
might melt/warp the plastic throttle tube.)
An off-the-shelf solution is to
buy a Heat-Troller or similar and hook that up to both
elements on both sides.
A DIY solution is to buy a $3 PWM
(pulse width modulator) on Fleabay and use a knob in a BMW
switch blank to have variable heated grips hooked up to both
elements of the Symtecs.
