Shiney,
Have you fitted them yet. I am interested as I need to replace the Hot Grips (US version) rather urgently. Went for a ride today and my gloves kept sticking to the grips, they have turned sticky and the rubber (well it was) can be scraped away to expose the heating elements. The supplier will not supply to outside the US anymore which is good because it forces me to look at other options.
BTW when I fitted the heated grips, I used the Gold Wing units which are greater in grip diameter as well as being longer by some 18mm. Using Bar Weight Extenders means that you can use the original weights, overall a wider handlebar postion which has helped me.
Keen to hear your feedback.
