Fortunately, the 749cc, liquid-cooled High Output Revolution X motor is pretty sweet, if a bit generic feeling compared to the Evolution motor. With 61 hp and 44 pound-feet of torque, it’s got enough guts to feel sporty in its own right. It’s torquey, surprisingly smooth, and the larger inclined vee angle makes it a compact package (from top to bottom), which was Harley’s intent in the first place. It’s not the most visceral feeling V-twin on the block, but a louder exhaust would help give the impression of a brawnier personality. Of the group, the High Output Revolution X engine revs the freest, backing up its more aggressive stance.
