Evo Evolution | Revolution Performance
Ever since Harley-Davidson first rolled the Evolution-powered Big Twins off the assembly line back in the 1980s, builders around the world have used it as the solid foundation for some truly great custom motorcycles. The time-tested design lives and with the new generation of riders getting their hands on these old Evo’s, they want every last drop of power they can wring from these motors. Revolution Performance’s full line of Evolution products and services lets you do just that.
Revolution Performance all aluminum Nikasil plated cylinders are able to take the stock 80-inch Evo to a strong bolt-on 85-inch big bore. For the late model Evolution engines Revolution Performance offers a 100-inch Monster big bore kit that reportedly creates over 100 horsepower out of that old Evo mill. If yours is already running a 4.625-inch Stroke crank, their our bolt on Monster kit takes your ride to 109″!
