Detractors like to say that Harley-Davidsons haven’t changed in a century, and that’s only partly true. While the classic 45-degree V-twin architecture originated on the 1936 Knucklehead, it has been continually refined. This latest version, called the Milwaukee-Eight, is equipped with a fuel-injected, twin-cooled (meaning oil and water), four-valve-per-cylinder engine that could almost be called modern. Holdovers include pushrod valve actuation with forked rockers and hydraulic lash adjustment, plus a non-unit six-speed gearbox. Even so, power is markedly improved from the previous generation, the 107ci (1,750cc) mill pumping out a credible 77 hp and 98 pound-feet of torque on the cursed CW dyno. That’s a far cry from the 50-ish horsepower Big Twins made not too terribly long ago.
