Hi Tim. Chinky china man heated grips, careful ya bike don,t go up in flames :-) :-) I can however give a big thumbs up to oxford sport heated grips, I,ve used for the last three years (mainly on my trumpet speed triple) as I usually ride the whole year round whenever time/kids/wife allow. These along with a heated vest are absolutely ace, keep ya kidneys and ya fingers warm and you can ride thro the coldest of days without to much discomfort/complaint. Plus the oxford grips are that good they feel just like a standard grip to touch/feel, not like those things you used to see years ago that were two to three times the diameter of the standard grips. Cheers. Michael
