Bore size – 3/4 – good for dual caliper front end set-ups. Sleek styling, smooth control and quality craftsmanship – thats what describes the H.E. Series Hand Controls. These units are slightly smaller than our Classic Series Hand Controls, for builds that require ‘a little less meat’ around the handlebars. Match with our pre ’82 switch housings for a perfect set-up. Finished in Show Polish, Chrome or Black Anodize.
