Harley-Davidson® Street Bob™ Vivid Black

Revolution X^™ Engine Heritage

The Revolution X^™ engine you see mounted in the frame of the Harley-Davidson Street^™ 750 motorcycle is all new, but the knowledge that built it wasn’t born yesterday. We are the Harley-Davidson Motor Company. We earned our stripes building liquid-cooled V-Twin engines the hard way: on the racetrack and on the street. We’ve been refining the liquid-cooled V-Twin power plant in the V-Rod^® motorcycle for more than a decade. And we’ve been refining V-Twin engine power for generations before that. The Harley-Davidson^® V-Twin is more than an engine. It’s an icon. Respected around the world for its reliability. And loved by riders everywhere for the feeling that only comes from turning the throttle on a Harley-Davidson^® motorcycle. The new Revolution X^™ engine is taking Harley-Davidson to a new place, but its soul remains the same.
